That would be...gutsy. If it works, it will be a huge hardware edge that will blow the PSP away completely. I've hated the 3D trend, but have kept my eye on Parallax Barrier displays (though so far, I thought they were cost-prohibitive). If Nintendo is going to roll one out on a handheld, it would be the biggest jump in hardware they've ever had on their competition, and probably the biggest graphic boost on any system since the switch from sprites to polygons. If they have an affordable parallax display for a handheld, and a graphics engine that can use it with comparable graphics to the Gamecube or PS2, they might just crush the HD phase of gaming right there (slim chance maybe, but a chance).
