As a press conference, I liked it. Games, games, games, that's why I am watching. Good pacing and very well done when they choose to do stage shot vs full screen video. Other companies should take note. Quite a few extended gameplay sessions too.
MS seems to have back/forwards compatibility figured out. As someone that has heavily invested in the Sony platform, it definitely feels like a 'grass is greener' situation. Right now, I wished I was on the Xbox side. PS5 needs to have this figured out, or I will seriously consider switching.
Even on a non-1080 stream (GB) it was clear what extra's One X had to offer.
That leaves the only real downside of the the press conference... $499. While a totally fair price to ask, it most likely will have difficulty finding market share. For me, it's not a price point where I would jump in as a secondary console and the exclusive library still isn't enticing enough for me to even consider it at a lower price.
I'd rate this conference a solid 8.5/10. Sony has to bring it, and show a load of titles that will release within the year and/or have a big surprise (PS+ shake-up) to be on par. But I very much expect a lot of stuff we already now about and the standard FIFA, COD, BF presentations.
