If Wii U only sells 15m, how well will key software sell?

Hard to say, but you can pretty much guarantee every WiiU owner will buy pretty much every 1st party game (cause they ain't buying the third party games) so they'll sell very good.

Hard to say what 3D World's legs will be, but there are 4m owners out there and it's sold to around 12% of the userbase? Surely it'll see a similar attach rate as the userbase grows?

It'll have legs, not huge legs like many thought though.
