Sony's real message of the night was the fact they learned there lesson. That meeting was basically geared toward the developers and community. MS will still drive home the fact that it's a gaming console imo
I think they'll drive home "everything you had on the 360 is here, including gaming, and more!"
I think people are underestimating MS' approach more than anything, and now that PS4 hype has significantly died down in mainstream press, and certain missteps in the announcement are becoming more and more clear, all they've done is given MS the upper hand to fill the holes Sony failed to in their initial, premature reveal, such as showing the box, 3D camera capabilities and showing expanded media capabilities. MS wants to fill in all the blanks at once, Sony wants to do them sequentially. Does this mean the gaming blank won't be filled in entirely? Not necessarily. When it comes to an actual presentation, games still take up the bulk of the time, and always have. Much of the other stuff is mentioned in dramatically presented bullets or brief demos, and I don't expect that to change.
In my head, press will forget about the PS4 when Microsoft shows their Kinect-based UI, fancy media switching and running multiple games simultaneously, and the sizzle that will bring in the mainstream press vs. Sony showing a bunch of pretty games and 8GBDDR5 will be much larger. What will the majority of gamers favour? Impossible to say until we've seen the games themselves, which will still be the deciding factor.
TBH I think MS has the upper hand right now because I agree with their strategy, it just remains to be seen if they have the better software, of which I don't have much confidence if I'm not looking at rumours and just looking at the past few years of exclusives I care for.
