Wii U could probably sale an extra million if Nintendo ports all their classic games into the eshop

They have some of the major classic titles on Wii U already... and even if you can't get them on the Wii U VC, you can just as easily buy them on the Wii VC and still play them off your Wii U...

I like the suggestion though, but I don't think it does much to sell hardware.
