Xenoblade on Wii sold around 950k.  And that was with a slew of problems and limitations faced in the West and Nintendo having 0 confidence in the game. 

Fixed.

Even 950k on 100m instal base isnt too great and we still got new game.

And now that Xenoblade is in the VC, we can expect it to have a nice boost in sales.

I think it will sell around 1 million as the predecessor, but Animal Crossing Home Decorator (or what is it called) will sell incredible and dominate the holidays.

maybe 1 mil life time it is possible!

So people actually believe that Nintendo shipped 420,000 copies of Xenoblade to just gamestop.

...Ok.

In april 2012, the game never charted on the top 10 of NPD and the top wii game was Mario Party 9 at number 7.

Honestly if Nintendo advertise this game half of how they did advertise Splatoon it still could sell 2 Milion lifetime imho

It well sell good but not great, even if they marketed this games like crazy, it will do good but safe to say it will far better then the Japanese version.

How did bayonetta2 bomb hard?

It sold almost as much as on the 360 or PS3, on a platform with less than one fifth of the install base.
Granted there was nothing remarkable about the sales but they weren't that bad.
