I'll be happy if we get Cyberdark Impact!, the other support cards seem a bit too much to just add to the card pool but one can always hope. I really look forward to the rewards...not to much the event though.
Cyberdark Claw would be pretty harmless currently (and probably for quite a while yet). It doesn't search much (given we probably wouldn't get Inferno, its ONLY target would be Impact), and nothing we're likely to get any time soon benefits from being dumped from the Extra Deck.
Most Level 45 rewards aren't that bad. And really, the varying power level is mostly just a consequence of how often level increases happen, the cards aren't going to be all of equivalent power.
I'd expect the Level 45 to be one of Chimeratech Fortress Dragon, Cyber Twin Dragon or Cyber Eltanin.
I wouldn't mind the lack of support as I see them as more of a showcase deck than competitive material. I'm reeeeally into showcase duels 'cause they seem the most fun. I can't wait to summon Cyberdark into Five Headed again.
