Lol. Microsoft hasn't won shit. Preorders in the US are 4:1 in favor of PS4. In Europe it's 8:1. Believe it or not, price makes a pretty big difference and like I said they're having major supply problems. PS4 is launching in TWICE as many regions. You're greatly overestimating the FIFA thing. Once people get over their initial "omg megaton!" reaction and start to use their brain to do basic math they'll realize that a PS4 + Fifa is still a better value.
Also the FIFA deal is only for preorders as MS has essentially stopped taking preorders in most places since they don't have the supply.
