I expect Halo: The Masterchief Collection to outsell all of Sony exclusives combined this holiday!
The upcoming Halo collection should be able to sell at least 5-6 million this holiday.
Drive Club will probably sell 600k this holiday.
LBP3 will probably sell 2.5 million this holiday on PS4. What else does Sony have? I guess some people will count Infamous Second Son leftover sales and Killzone Shadowfall so we can add another 200k to that list. That puts Sony at 3.3 million and Microsoft at 5 million. Not to mention Microsoft has games like Sunset overdrive, Forza horizons, Dance Central etc. But not counting those even, Halo should dominate the first party charts!
