In a perfect world...! 
But seriously, an arcade/console thing wouldn't work. If people had the option of playing in their own homes, that does a lot to kill the possible sales on the Arcade side. Arcade operators would not be pleased by this type of thing (they have to pay out plenty of money for those arcade cabinets and PCBs, after all), which is why the usual rule is to give an arcade version of a game at least 6 months to rack in those quarters and keep said operators happy.
I mean, believe me: I'd love nothing better than to be able to play Gundam EXTREME Versus asap. And with the game being built on Namco System 356 (PS3-based tech), a PS3 port would be easy. But Bamco and Capcom want to make that money, and the Arcade owners want that return on their hundred thousand dollar investment, so I and others gotta wait til next spring at the earliest. 
True, but I'm just being greedy on this since I know that there aren't many arcades left that would actually buy new games, but I'm sure mine would get it since they get a good amount of money from the Marvel games and actually get stuff that's newer than Neogeo/CPS2 games

Yeah, but for example, I don't have a classic controller, simply because I don't feel like buying an extra controller just to play a few games differently.
If I didn't have a Gamecube controller, I'd be boned when it comes to TvsC.
And that's why I say that they should've made a damn bundle like MHTri did.
A Steel Ball Run-themed (or otherwise Jojo X-over) FG would be the answer to a long-standing wish of mine. Capcom, Bamco, ASW, whoever; give me a new game! The SBR manga stands to ends some time in the near future, after all! 
But after the last 2 Jojo games on PS2 (which both used 3D graphics), it seems clear to me that Araki's style really only works well in a 2D style. No matter how much Bamco and Capcom tried, rendering Araki's eccentric designs doesn't seem to work well in a 3D space.
SBR is almost done? Man they really need to hurry up with those scanlations >_>
And yeah, Araki's style can only be done justice in 2D...give the license to Arc then

(Hey, HnK was awesome even though it was so broken that not even all of the duct tape in the world could fix it
