With an article name like that, I would've thought the author would AT LEAST bring up specifics as to why we should be worried....like mentioning the infinites that some characters can do.
NR Studios already know about some of the infinites and are doing a day-1 patch. This is why people that post exploits on youtube are doing devs a favor by helping them know about this stuff.
Anyways, let's look on the bright side - it's highly likely that the game won't end up being as broken and scrubby as MvC3. MK9 is being put under abit of pressure because of their past games and the fact that they really haven't proved themselves capable of being able to make a real competitive fighter. It's 2011 and even though it's an old game, SSFIV has really raised the bar on what a "competitive" fighting game should be like.
With downloadable patches being the standard way to fix almost anything in today's games, it'll be interesting to see if they take full advantage of it.
On a random note, who are these "FeedYourConsole" peeps?......
"Cons:
Overwhelming number of moves to memorize for casual gamers (Hardcore fans will love it)"
Really now?
