Nintendo is changing alot and will bring enough games in the coming years to avoid the drought that caused bad console sales in the past. Wii u is an amazing system and will clear 15 easily in 2015!

Lol not sure if serious. 

People nowadays use the "not sure if serious" comment too often. It's supposed to be used when someone is exagerating about something, which hardly is the case. Aside from "Nintendo is changin alot" which is his view and "will clear 15M easily in 2015" which is his opinion on the subject OP asked, the rest is pretty much factual.

As for the OP's question, given Nintendo has sold in 2 years 8m plus, going by the same ratio, it would achieve +16M in 2016. Now since I believe it might sell better during 2015 I think it will surpass 15M before holiday 2016.
