Amazing thread. Good job.
The Wii U will sell well in Europe in my opinion though its the U.K. market that Nintendo needs to convince. Germany and France are pretty much pro-Nintendo country so hopefully Nintendo can get its act together and act fast for the UK.
As for the U.S. and Japan, it will sell all its shipments until the end of the holiday season, that's a given.
By year-end, Wii U sales should end up towards 3-3.5 million give or take or am I too optimistic? :s
