10m+ if the WiiU HW can sell decently,say 60m

8m if it stays to a small niche like the N64 or GCN

I find these kind of prediction threads a bit pointless. I've got nothing against predicting lifetime sales, but not only are there a multitude of unknowns, but these kind of things take forever to pan out. First-week, first-month, even first-year seems reasonable, but by the time sales flat-line, most people will probably have forgotten about their predictions here.

With that said, I'll still predict...

6 million. Max.

Ya I guess they are a bit pointless but its just for fun. I like seeing the differences in opinions and possibly some nice discussions.

in the 7mil range but probably more if things go well

6.5m

Not so much the threads themselves as their quantity. And some people taking these sort of threads too seriously.

My only problem with predicting this game is that there's not a whole lot known right now, and the Wii U is a little too uncertain for me to be entirely confident about my prediction.

My prediction may be a bit high but I like to stay optimistic. I think 5m is pretty low tho, Sunshine on Gamecube did 6.3m so Wii U would have to sell like 15m lifetime for 3D World to sell that low.

Hint: The WII U is selling worse than the gamecube as of now. I hope that helped re-evaluate your prediction.

Your forgetting one thing though, it's doing worse than gamecube in the same time frame. I am not joking and I hope your hearing me right. 

I'm aware. But at the same time, the Gamecube came out over a decade ago. Direct comparisons between consoles so far-removed are troublesome, at best.

I have my expectations fairly low, all things considered, but I don't understimate Nintendo IP without good reason.
