Not going to happen, you see. I live in Europe and the playstation brand is so huge and popular over here and I don't see it changing because win 10 compatibility with Xbox. Most of the console owners or at least going by people I know don't care so much about PC. Also people get the console their friends have so they can play with them and going by that it's maybe to late for x1 to catch up in Europe sins ps4 is doing so well in every country over here. We are fifa nerds over here and fifa is so heavily advertised with x1 now days and that did not even help x1 to sell more, so I don't think exclusives will matter that much in the end, not even Halo. But however I can see a huge price cut make x1 more wanted over here but even then it would be hard for it to outsell ps4. UK is the only part of the Europe where X1 is as popular as ps4 and that's because of the crazy deals they have been offered and to be fair UK was a xbox territory in past gen so I guess that has something to do with it too but in the end ps4 will eventually get a price cut too so meh. so for now, you are crazy ;)

Sony have dropped their $280m (of my memory serves) annual advertising deal with FIFA which is gonna have an impact too...Football is massive in Europe as you know
