Vita shipments should be around 3.25M for 2014 and are a minimum of 600k undertracked here in VGChartz
(Link: http://gamrconnect.vgchartz.com/thread.php?id=197740&page=1# nanzano explains everything very good). Let's say Vita sold 3M in 2014. Wii U did in 2014 3.66M and sold 660k more than Vita. Wii U is at 8.83M and Vita at 10.3M Global in the end of 2014! This is a fact!!! The gap was 660k between both in 2014, let's say the gap will be also 660k in 2015 (even if this is impossible in my eyes, 2014 was the peak year of the Wii U and Vita will have a very big 2015 in my eyes), Wii U still won't be ahead of the Vita. Even if the Gap will be 660k in 2016 the Wii U won't beat the Vita!!! So you see even with the 2014 Gap (which was definitely the biggest Gap between Wii U and Vita in their lifes) Wii U has no chance to beat the Vita. The Gap will probably be minor in 2015 so I see no chance for Wii U to beat the Vita!
What do you think?
