Xenoblade had the potential to sell 1.5-2M, if it wasn't for the very limited stock, then X, if manages to be the ultimate next-gen JRPG (like how Xenoblade was the one for 7th gen) has the same amount of potential.
Bayonetta 2 had alot of exposure already, thanks to all those fanboys raging all over the internet, we could see decent sales. (1M+) Wii U has mostly hardcore Nintendo fans at the moment, and this trend will continue. Thus, sales shall be better than expected.
Also Miiverse helps a lot with game exposure and decisions making. (Don't forget there is now potentially 45M Miiverse members now)
