Several sources have indicated to me that PlayStation Neo launches this year, despite its E3 no-show. If that is the case, it'll be interesting to see how developers utilise its resources, and whether 4K really is the focus. And we can be equally as sure that Microsoft will be watching just as intently as it gears up for its own next-gen roll-out.
Notable upcoming gaming events with big Sony presence:
Gamescom - August 17-21 [2 months after E3]
Tokyo Games Show - September 15-20 [3 months after E3]
Paris Games Week - October 27-31 [4.5 months after E3]
PSX - early December
