Why do people like thumbs-downing comments because they reveal facts that someone doesn't like? As I said, a Cell would be a bad idea for a mobile device; it works well for the PS3 because it's sucking juice from a wall outlet. In a portable, that just means we'll be looking at a 90-minute battery life.
It's also kinda ironic, since I wasn't exactly bashing Sony, but rather, hoping that they'd make a choice that'd make the PSP2 GOOD, so that it might SUCCEED.

I'm kinda dubious about it being "HD" unless it's particular large, or Sony goes through the extreme expense of taking a super-high-density LCD panel. The PSP and PSP Go had a resolution of 128 and 145 dpi, respectively. (for comparison, the DS/DSis ranged from 76-107 dpi, including the XL, and the 3DS is 133 dpi)
If they didn't go any higher, then the PSP2 would need a 10.1" (8.8"x5.0") display to do 1280x720, making it the size of a netbook. Granted, they could shell out for a more dense screen; the iPhone 4, I think, holds the current record at 330 dpi. With something like that, a 4.45" (3.9"x2.2") display would work. However, such high-density displays are INCREDIBLY expensive compared to lower-density ones of the same size; expect such a PSP2 to cost >$500US.
So chances are, at the very least, we'll see "HD" in the way the Xbox 360 typically does it: sub-720p. (most top-shelf games like Halo: Reach render at 576-640p, and stretch to 720p) If they combined a 576p resolution with a 180 dpi display, comparable to most less-expensive smartphones, then it'd need only a 6.5" (5.7"x3.2") display, and this would make a price closer to $300 plausible. And seriously, on such a tiny device, true HD is more or less wasted, and just a place to make on-paper number boasts.
