A new type of unlock event that is said to be based off the original series. Based on the name this might refer to the Duelist Kingdom arc from the anime and manga. Additionally, we will be seeing a new type of duel and be able to unlock a new playable character, speculated to be Yugi Muto.
Let the Mayhem Begin [Mid-September]
Based on the manner of speech written on the text, the new event is most likely a variation of Rex Raptor, similar to how Super Joey was to Joey Wheeler and Elegant Mai was to Mai Valentine. Based on this, he will most likely be a roaming LD with drops different from the usual Rex Raptor.
New Upcoming Event [Late September]
A new type of event, that has never been released before, seems to be planned for late September.
The text reads a "mysterious tower", combined with the fact that this event will most likely precede a Halloween themed event, this event will likely be related to Soul-Absorbing Bone Tower.
"Face them with new strategies and techniques" might refer to a new type of dueling or challenges not yet seen in duel links.
An update planned early on in October, will be adding many new features to the world of Duel Links including:
Addition of a new world.
Addition of a new character
Addition of new missions.
Special Login bonus.
"Addition of a new world" might refer to the addition of YuGiOh GX, based on the recently datamined image.
Since "Addition of new characters" is planned just before October, this might refer to a Halloween themed character, Bonz maybe?
"Addiition of new missions" is quite vague, it may refer to a new type of mission that is yet to be seen. Or maybe new stage missions that will increase the stage cap. Worst case, it might only be referring to extensions on the lifetime missions(e.g. Login for a total of 1000 days).
"Special Login bonus" is very self explanatory. You login, you get free stuff. Although would this be permanent or a temporary event, similar to card flipper events.
Event: "Duel-a-thon" [Early October]
Duel-A-Thon will be held again in Early October. During the event period, you will earn points every duel, to fill your "Duel Meter". Gather points every day and get daily rewards, accumulate those points over the course of the event to get even bigger prizes.
A new character coming to Duel Links! [Mid-October]
Mid-October would be releasing a character "fit for this time of the year", if we are going with characters from the original series only, this almost 100% confirms Bonz as the new unlockable duelist. Adding to this, the dialogue written saying "Dueling me will give you a spook that will put you in your grave", further solidifies the speculation Bonz will be released.
How. Honest question. How did the other generations turn this game into a laughing stock? This game has ALWAYS been influenced by generations beyond the first. It's not like Sphere Kuriboh was released in Metal Raiders, we got it in Dimension of Chaos, an Arc-V set.
Then don't bother using cards from the other series too. You hate then, eh??? Destroy all your cards from either series like Sphere Kuriboh, Asura, etc.

Vjump spoiled the upcoming event, credits to ygorganization for translation and Maxut for the leak.
"The next upcoming major event is “Ijigen no Tou”, i.e. Different Dimension Tower! It’s based on the premise of “Continuously Dueling while keeping the same Life Points from Duel to Duel.”. Gather Mission Points from this event to collect cards and Gold."
I also noted D.D. Guide near the replay.
Big Five, Oricalhos, Shadow Riders, those are also possibilities.

Since I can't figure out how to reply because I'm stupid, I'll just separately post stuff that I found in the audio files on top of Anonyboys stuff.
Ishizu uses Gravekeepers Descendant & Kelbek
Some audio for what sounds like a machine 3D Animation
Odion uses Mystical Beast Evolution
Mai uses Harpy Queen, Dancer and Cyber Harpy Lady, as well as the Seal of Orichalcos.
Tea uses Magic Formula and Mystical Space Typhoon
Yami Bakura uses Zola the Spirit and Dimensional Fissure
Yami Yugi uses Magical Dimension, Swords of Revealing Light, Mirror Force, Magic Cylinder and Monster Reborn
Odion has a line for Eatgaboon for some reason
Npcs have more lines
Listening to the audio files in the google drive which is linked to in the Reddit that Kryo has given us in a lower comment. A few things that stood out, in the order I ran into them. Some are way more intriguing than others. (I might not be the first to notice most of these):
Multiple NPCs XYZ summon monsters.
Kaiba summons Obelisk.
Mai summon Harpie's Pet Baby Dragon.
Yami Marik says "Egyptian God Phoenix!"
Yami Yugi summons Horakhty.
NPCs Synchro Summon. In order to lend credibility, the data file as provided in the Drive folder is 0ed379e2.wav. I'm not doing this for all of them because that would take forever.
Yami Yugi uses all 3 Egyptian gods (separately).
Odion summons the End of Anubis.
Various playable characters Pendulum summon.
Bakura uses Necroface.
I'm fairly certain Odion summons Ra.
Yami Marik summons Newdoria.
Pegasus activates Thousand-Eyes effect (He might have already used it---I didn't fight him lvl 50 during the 2nd gate event)
Yami Marik uses Ra (sphere form)
Mai SPECIFICALLY XYZ SUMMONS HARPIE'S PET PHANTASMAL DRAGON. First specific XYZ summon I found.
Mai tribute summons Ra... OK Why not?
Bandit Keith summons the Wicked Eraser.
Joey uses Jinzo (NOOOOOOOOOO)
Bakura uses Macro Cosmos.
Then I realized there was no chance in Hades I would ever finish listening to all the files, so I stopped. But still, nuts stuff.
Oh, and that stuff was posted 7 months ago, Kryo, and provides NO support for TryHard's statement.
