Forza 6 is just barely out pacing forza 5 when you align sells. So both games will end up around 2.4 million ish. Yet you expect 7 to do only2. You also expect all forza games to stop selling copies I guess. Your 10.2 should really be about 13 when these games actually finish selling copies. And that's also retail only. So u expect gran turismo sport to do 13 million retail total like 20 million(including digital). That seams pretty high sales for anyone to expect.
Halo MCC will sell 5+ million copies(including digital)
halo 5 will sell 10 million copies(including digital)
x1 will pass ps4 in USA, and UK.
