I haven't seen anyone recently saying that it's going to make some kind of momentous comeback and defeat the XB1/PS4, if that's what you're insinuating.
As for me, if it sells equal to or more than the GameCube, I'll be happy. Even if it doesn't, I'll still be happy. You know why? Because I'm getting some kickass video games that I love, and that's all I could ever ask for in a video game console, regardless of how much it sells.
