Probably Vita first, followed by Wii U. Only thing that's for sure is the X1 will do it last (at best I can see it hitting maybe 8.5 million this year). It won't hit 10 million till mid 2015, and close out 2015 with around 14-15 million. The Wii U will still be ahead for many more months to come
I don't get why people think the X1 will have a bigger boost. It sells in NA and Uk but that's it, when taking the whole world into account, PS4 will have the biggest boost with Nintendo probably having a good shot at one too.
