Interesting, but they would have to come with something BIG.
European exclusives (witcher, cyberpunk, other eurojank shit they could get) , multiplayer for free, service to match PS+, cheaper price then PS4 (360 was cheaper then PS3 and yet got outsold so the price would need to REALLY cheap), no online needed bs, no focus on services that don't exsist in Europe (Netflix).
It's an uphill battle and as Oscar says outside of English speaking countries Xbox has it tough.
