Online Play would be nice, but I doubt it. In fact, I wouldn't be surprised if the reason that their XBLA releases never came stateside was from making the game compatible with US servers and such (I mean look how games like MI2 are missing Online Play in the US versions)
The Wii however lets them port games from their library simple and effectively. Once they work with Nintendo and get their "emulator" up and running aside from testng and releasing "roms" it's just a matter of making up a manual for the game like what's available in all the other VC games (movelists and the such would be great)
I personally don't mind them taking that route at all.
