Yea I agree with Opitek & Belmont. Nintendo is no fool, and they'd definetly understand that they'd piss off a very loyal fan base if all of their VC games would not transfer over to the next console. The only thing I could see preventing that, is if they didn't include a Virtual Console at all, but because of the big success of it, I'd find that hard to imagine.
You can bring up the argument, "well they're right now making us pay for them again." But that's a little different. These games are more than decade older, so aren't going to directly piss people off for having to re-buy them, and they;ve been emulated so that they can be digitally downloaded and stored.
