They would only put portable games. Nintendo has almost never crossed Console and Portable game lines.
Sure you have the notable reports of Mario64, all stars, etc, but, they have almost always kept their SW separate.
Example, look at pokemon. The portables are far better than the console versions and clearly different types of games.
For VC Wii will continue to contain and grow in purely console based games, while DSi will, hopefully, begin to carry only portable based games.
So, I'd expect to see GB, GBC, GBA, Gamegear, lynx, etc eventually on it.
