due to there only being 12 Million wii U sales on earth and most if not ALL are hardcore Ninty fans (becuase lets face it no one else bought the system except die hards)

I expect 1.5 Million.

500k or less.

Definitely over 1m

I think it will be between 500k and a million unless they advertise it very well.

500k -1m

Somewhere between 1-1.5 million is a safe bet.
Fans have waited 8 years for this game and the distance in time between releases could draw in some new fans to the series.

How well did SF64 do on the 3DS?

500k-1m. If that.

Less than million.

That's probably 1m with digital factored in. I don't know. The Wii U has such a high attach ratio, but I don't think this game has been well recieved. I guess we'll have to see.

I think you're overselling the turn around a lot. I haven't seen any coverage of the game that sounds fully convinced of anything, and I've watched everything. Everything. Everyone who sees improvement are still weary, and there is no full confidence in it from anyone. And again, I'm not talking about what I think of the game, because I think it looks awful. I'm talking about the big media companies and personalities, and I'm talking about commenters. I think it's fair to say that there's an almost universal sence that the game has improved graphically at least a little bit, my opinions aside, and I think it's far to say that some people think that the gyro controls were improved a bit, but there definitely has not been this massive turn around of public opinion, and I still find it extremely hard to believe that this game will end up reviewing well, especially when Splatoon review as lukewarm as it did with seamingly less problems.

I don't think Star Fox Zero's complete time is going to review well, I don't think its controls are going to review well especially since the gyro is not optional, and I don't think that retelling the events of the Lylat Wars is going to review well. I think that's going to hit it's sales potential pretty hard, because Star Fox is not the kind of IP anymore that's going to sell a lot on it's name alone, regardless of critical reception.

Star Fox Command sold only half a million on the DS. Just 500k. And that was a new campaign on the most sucessful Nintendo console with gameplay that resembled SF64 more than anything in the franchise since. It tanked, and that's a game that got a 76 on Metacritic. SF0 is not being treated what so ever as this second coming of Star Fox, or a return to form. It's being treated as a game with too many caveats, and if that doesn't review well, that's going to hit its sales just as badly.
