From what I have seen people say, the Xbone and PS4 will outsell the Wii U by the end of this year?

Doubful, simply because I doubt they can produce that many systems for launch.

The PS4 will come closest, right? So here's how I see it going:

W1: 700k
W2: 480k
W3: 780k (EU launch)
W4: 500k
W5: 580k
W6: 300k (last week in the year)

Total: 3.34mil

So I'd say it should be around 3-3.5mil come the end of the year, and the XBone about 1mil less. Whereas the Wii U should be over 6mil come the end of the year.

Just my personal thoughts, but I don't see it doing better than the Wii. That thing was literally an explosion of excitement, most importantly, outside of gaming circles. And I do believe both new systems will hurt each other sales-wise.
