My predictions for March:
[Early March]
A new character is coming to Duel Links!
Obelisk Blue student Syrus Truesdale is making his way to Duel World (GX)!
"Hey guys, wait up for me!"
[Mid March]
Obtain a Legendary Duelist
A certain dolphin is going to be unlock in Duel World (GX)!
"You can just call me Aquos if you'd like!"
[Mid March]
Obtain a Legendary Duelist
Unlock a returning character in Duel-A-Thon!
"If you stand in my way of victory, you'll pay the ultimate price!"
[Late March]
D.D. Tower Appears
"D.D. Tower: Wind Dimension" coming soon!
Various updates have been made based on feedback we have received!
Aim for the top knocking down any formidable enemy that may stand in your way!
[Early April]
Obtain a Legendary Duelist
"Duelist Chronicles: Battle City Begins" is having a rerun! If you missed out on unlocking Arkana, now' your chance!
"No one has seen my best tricks until now!"
It all seems credible, except for that dolphin part. There are too many characters they should add before that, and they'd also have to add Neos as a character.
Also, I'm pretty sure blue Cyrus will be a special roaming event, like elegant Mai. He'll probably be unlocked in his red or yellow outfit.
I dont see see Neos being a Legendary Duelist but rather Aqua Dolphin's ace. One monster can be used as multiple Legendary Duelists' aces. Ask Seto and Mokuba Kaiba.
