As I stated earlier, many of your games can't come out for legal reasons (for example, any game owned by Rare will never come out, like Conker and the Banjo games since Microsoft owns them now). Nintendo also can't just take another publishers game and put it up, that publisher has to want to do it. It's also not as easy as you think it is. There is also no reason WiiWare and VC can't exist at the same time, and most WiiWare games are not from Nintendo anyways. So it's not like they are using up time or resources on them.
