Going to miss the features of XBox Live. I'm not 100% set on other competitiors offering such a great online experience. To me, XBox Live was the king of Online and will always will be till someone betters them. Other companies have offered great features, hell Iove the Mii Verse on my Wii U, but it doesn't stand up to what Microsoft offers.
As far as games go? It's a tough call. I wouldn't miss much from recent games - Halo, Gears (Judgement was just flat out bad imho so I won't miss it as much), Fable (Fable 1+2 are golden), and I'm sure as hell I'll enjoy KI and the newer Kinect Sports games. But Microsoft's lineup has always been below the quality of what Sony and Nintendo have offered, and that's coming from a MS fan. However, Microsofts saving grace to me is still what it has for online offerings.
The system structure itself? I think the XBox360/1 controller is the best on the market and the best thing going for the XB1. Not the system or Kinect itself. So MS has that.
I'm hoping the XB1 will prove me wrong but the majory strong points for MS - Online Infastructure, the bad ass controller, and Halo. Believe it or not those things were really key for me keeping up with the 360 and not buying a PS3.
Depending how MS moves forward after their 180 I might miss them dearly, or be content with just owning Nintendo's next system and a power house PC.
It's just that simple.
