While I don't believe that WiiU will do as much of a turnaround as PS3, here is what is has going more so than Gamecube that can help it be a "late bloomer".
- GameCube went down to 100$ during the same timeframe as WiiU is now, so WiiU has more space there that can cause a bit more of sales.
- Nintendo seems to be doing a lot of bundles with WiiU which are helping it, while with GameCube it didn't have as many as WiiU.
- Console revision, Nintendo seems to be doing more SKU's now, GameCube only had one, Nintendo had two Wii's, more for DS, and even 3DS got a "new" model, I believe we will see more revision for the WiiU aswell, I believe we might have a Gamepad-less SKU near the end of it's live, just so Ninty can squeeze out as much profit as possible from this gen.
While I don't see it hitting 50 mil, unless amibo or something else really become a huge craze, I believe it can sell around N64's level.
