Hmm... Mysterious names...;)

What the hell is half of this stuff?? And is a Kinect 2 really necessary? It's not like most of its userbase is going to care about better graphics

What is this supposed to be? leaked info or something?

Please, can someone tell me what those abbreviations mean?

The ones I know:
+CES_Consumer Electronics Show
+MIX_ This is Microsoft's conference.

The one I think I know:
+MWC_Mobile World Congress? If that's so, then Tango and Apollo are supposed to be the successors of Windows Mobile?

The ones I have no clue:
+ONM_ ??? (I doubt its the Official Nintendo Magazine)
+OSN_ ???
+WPN_ ???

Until then, I agree with the timeline of Windows 8, and I disagree with Windows 9 (they won't anounce it the same year they launch Win8) and the nextbox, they won't announce it at E3 2013, it will be earlier (maybe GDC 2013 or even E3 2012).

And WTH is the Xbox Store?
