Or the Wii series. Every game in that series would be replaced by a different game (New IP or series that didn't come to Wii) So basically GameCube 2.0.

That was too easy.

Give us a tougher question, Nintentacle. 

Wouldn't it be around 100 million, still?

I'd be at PS3/360 level due to Third Party Support, and an extra 20 million (GameCube sales) because of first party games.

Edit: Wait, I forgot to take into account that the majority of Third Party games don't appeal to Nintendo's core audience.

Except it would have done even worse.

Had they instead focused on the horse power of the Wii instead of motion control and made it an HD console and priced it reasonably (Miyamoto wanted the Wii to be a $99 HD console but good luck on that lol) it would have done well.

I'll do that after a few more threads are posted, I don't like posting 2 in a row.

With that price point and Zelda launch and probably HD visuals, a lot! If it was as expensive as the 360 though, then maybe not so much

Probably would have sold an extra 10-20 million to the current sales because then people can play madden and nba on it

This , and even worse I'd say 15 million

But it wouldn't be gamecube 2.0, it would be Gamecube again.  The motion controls were the system.  10m tops.  The Wii was a great idea that failed to fully capitalize on its success, and left Nintendo stranded in the following generations.
