Yeah his was a concern of mine as well, discussed in another thread. However, there are a number of reasons why I don't think button smashers will prevail in this game...
With the combo break system (HP+HK breaks Hard auto doubles, MP+MK breaks Medium auto doubles etc), I think it will be very easy to break out of anything a button smasher sets up. I have a friend that smashes buttons in DOA5 and I'm easily able to reverse everything he does because he's just smashing the same buttons and he becomes very predictable. If anyone is "predictable" in this game, they will be at a serious disadvantage.
If your button smashing opponent gets you in a combo, it should be very easy to break out of it because it will be predictable enough to counter the same moves they are smashing over and over.
Ken Lobb squared off against some girl and kicked her ass. A clear Veteran vs Noob faceoff. This shows that more seasoned players obviously still have the advantage.
Button smashers also probably will not realize that the attacks they keep repeating (and keep getting blocked) are also boosting their opponent's super meter which will eventually come back to bite them.
i think its funny they are "confirming" them slowly like its something exciting
we all know they are going to release all the characters...since............well........they charge money per character......***OBVIOUS ALERT*** more characters.....==more.....m....money
and hopefully any new characters.....will be FITTING to the KI "universe"
oh and about the anyone pulling off combos.....meh figures...it was easy in the 1st KI, but i always enjoyed the trial and error, in trying to figure out new combos....but i know day 1 the "go to" combos will be out, and it will be spammed...thus fun=ended-day one (not really but sorta)
