The big man himself piped up about Sony's new controller, and he shares a mentality not uncommon to the rest of the gaming community (judging from the reaction of Tekken 6 using such features).
In an interview with MTV, he believes it isn't mainstream enough for most games saying, "It's tough because sometimes you move the controller, and you don't [mean] to fly into the ground. You just want to put the controller down... People aren't that good at totally standing still. Even pilots actually sit in a chair when they do their flying. So there's a lot to be learned about these controllers."
Apparently there is. Microsoft would know, considering that they tried it already with the Sidewinder Freestyle Pro which was flagrantly mediocre. Sony's got their work cut out for them with this one. It'll be interesting to see how it's integrated with all of the "mainstream" titles, if at all.
