I don't think the Star Fox games were ever system sellers! It will probably help just a bit though!

No, but this could be a good chance to get the franchise back into the limelight. There's no reason they couldn't do, say, a StarFox cartoon. Indeed the franchise would be perfect for it, but people need to know who in the hell Fox McCloud is first.

It doesn't look like a big project to me. It looks like a small game. So no I don't expect it to be a big system seller.

No, from what I know they only put about one year of development time into this.  For all we know its just a downloadable game.

No. It reviews well it will be an asset to Nintnedo, no bigger system seller then pikmin 3.

Lol no, Xenoblade will be above the level of Bayonetta 2 in terms of selling consoles. It's a extremely niche game.

the first few sold 3 and 4 million globally respectively so they probably were system sellers to some degree

I dig Star Fox and am torn on whether or not to pick up a Wii U, it might sway me. I think like the others mention, Star Fox is sort of one of those die hard Nintendo franchises though that only prior fans for the most part will be nuts exited about. There are lots of shooters available.... I will say that the popularity of the roster of characters from Star Fox might have went up over the years though, especially with Falco in Smash

I expect a launch week boost and that's it.

There would be no bigger system seller than effective advertising...

It all depends on how many Star Fox fans you think aren't already committed to buying Wii U and is essentially factored into the Wii U baseline, with obviously a one or 2 week bump when the game releases. 2 Star Fox games on GC didn't do much for GC, and the best of those two games was early in the generation when it could have been one of the games to popularise GC. The 2005 game was did not review so well, And by then it was all over for GC anyway.

Star Fox can help Wii U maintain current sales, but it's not going to kick sales up a notch. In reality unless LoZ doesn't do it there's nothing Nintendo can do to improve the situation this generation. All the other big guns have been fired and we have seen the result with a 15% market share for the 8th gen home consoles on Black Friday.

With what's coming down the line for PS4 and Xb one for next year, LoZ and Star Fox will need to be all they can be just to keep that 15%.
