I can already go on the original Wii shop and get any game that's likely to be released. When the Wii U VC launches they'll probably start off with first party titles. Maybe even the same batch of games added at the start of the original Wii shop. Unless they add some games that aren't already available to download i'm not too excited for this.
Here's a few games I'd like to see that aren't already available on wii.
NES TMNT 2 and 3 Contra, Seriously what the hell Konami where is this game? Journey to Silius Willow
SNES Clock Tower Earthbound. For the love of god release this already! Secret of Evermore TMNT Turtles in time Aladdin Dracula X, Yeah i know Rondo is already available but the Snes version is good too. Sunset riders Mega man X3 Demon's Crest
GENESIS Castlevania Bloodlines, Once again Konami show some love! Contra Hard corps
Any one of these would be very welcome. What yet to be released games would you want this time around?
