It's not copying. If they made a PSP with two screens, a touch screen, gyro sensors or something like that, and 3D movie effects, THEN they'd be stealing. But they aren't, they're just using a type of technology that's been around for a bit and trying to improve off of it.
Also, my prediction is that this will crash and burn. HDTV's are just starting to catch on, and then Sony decides to try for 3DTV's without the glasses. You know, there's a reason things like the Power Glove and the Virtual Boy failed. It was because they were too ahead of their time and the technology just wasn't sufficient enough. I'll bet that this will be the same thing. Either they fail horribly and all that research and development goes to waste, they produce a crappy product, or the product will be good and end up being too dang expensive to make a profit off of.
Heck, about a month ago, I was at Best Buy or something (I can't precisely remember the name of the store, but it was an Electronics Store) and I saw 3DTV's that used the 3D glasses priced at I believe somewhere in the high thousands range, like 5000 or 6000 dollars. Imagine if Sony tried to make a 3DTV that didn't use the glasses, they'd probably get into the tens of thousands of dollars or they'd end up making it too cheap to make a profit off it.
