Lol.. so many Nintendo haters here.
Get over it, people.. the game is a 3Ds exclusive and will remain like this for some time, no matter if it was due a Nintendo-Capcom agreement or a sole Capcom decision. Remember Re: Revelations was also a 3DS exclusive.
Can´t you just instead of crying about this just..... praise the fact that some games still can drive a huge audience? This kind of launch were common during the SNES-Genesis days.... today we rarely see gamers so excited about a launch for lining up to get it, even in Japan.
This may be an indication that the future of this market may not seem so dim... at least in Japan
