I played a demo unit on the weekend, and I really hope the load times I saw were due to unoptimized demos.
Every game I tried took between one and two minutes just to get to the title screen.
I was really digging Virtua Tennis and Hot Shots Golf, but I'm still not ready to drop that much cash for a portable I'll barely use.
Also, when did the Wipeout games lose left and right air brakes? It just feels all wrong.
