Looked like a classic shirt from closer to Playstation's launch. Obviously, the assumption is that it was a hint, especially since they mentioned build the list, but no confirmation :\
I cant believe they ending on a fucking MOBA like it was something to give a damn about.
Like it was a decent show and then it just ends on some random game that should have been part of the Adam Boyes "and this thing is also coming to playstation" part.
