Well, what Im hoping for if this sells well (which I think it will). It will get Nintendo to start open talks with third parties to get those games that never made it to the VC.
Battle of Olympus and Crystalis are the first that pop in my mind for the NES, and I know there are others.
And if other systems do come out, we can hopefully get games like Lufia 1 & 2, Soul Blazer, Illusion of Gaia, Terranigma. Just to name a few.
But if there would be no way to add games to these miniature systems, it would be a moot point, anyways.
