Well, they moneyhatted the entire company then... because so far only two ports of Fighting games have been announced for Vita, while 3DS is getting a lot of love.
Super Street Fighter 4
2 new Resident Evil
1 upgraded Monster Hunter plus 1 new MH
EX Troopers
Professor Layton vs Ace Attorney - I think Capcom is making the story
Project X-Zone
And even "games" like Megaman Legends 3 that was killed not because of the 3DS show support
Capcom is simply giving more trust to 3DS than Vita.
