But that's a business plan. As for what they should do, creative-wise...honestly...just make a portable PS2 (PSP itself is NOT as powerful as PS2 despite what some may think). And I mean a portable PS2. Same tech, but portable. TV out at 480p for ALL games standard. Two analog sticks. Stick a touch screen in there if they want. Make it so the portable game system SKU has a UMD drive (in addition to digital downloads as is currently enjoyed). The phone and walkman can be DD only. The issue they have with PSPGo is that Go is positioned as yet another remodel of PSP, appealing to the same exact market of consumers (gamers). Of course those consumers balked at the idea. But with a PSPhone or PSP Walkman the consumers would be a bit different. They wouldn't balk at no UMD because the majority of them probably wouldn't be current PSP owners anyway. And, hell, some PSP owners might get a PSP2 AND a PSPhone. That's all they really need to do, IMHO. They don't need to "go different" like Nintendo. They need to just put out a portable PS2, two analog sticks/nubs/whatever, and have wholly separate SKUs in wholly separate markets of the industry operating in tandem. And they REALLY need to hash out PSN, as it will be PSN that "sells" more folks down the line on the product. And PSN should be rebranded as "Sony Store" or something. They have internal music and movie and tv studios that they can leverage, which is something Apple and Nintendo and MS don't have.
Knowing our luck it won't be this tech at all and they'll give us some really crappy-looking, unconvincing 3D image with a depth of 1cm. Come on Nintendo, make us happy.
The 3DS is unlikely to use just headtracking, though. With headtracking for a portable you'd need to tilt the device to get the 3D effect. Now, with some games (like adventure) tilting to peek around would obviously work brilliantly but for racing games for example, you'll need a 3D effect to pop out when the device is stationary. With this in mind it is very likely the device will use the new Sharp 3D screens, that way the 3D is in effect when the device is stationary as well as tilted. Racing games will be rather amazing with this tech, for once you'll actually be able to perceive the depth of the track and the corners, and not just interpret / adjust to the 2D image you're viewing.
