Sony's new handheld official specs...
I read the specs for this thing back when they were released at E3, and my immidiate reaction was that they are complete BS. Heres why:
PSP:
More mhz then DC or PS2 (333mhz vs PS2 300mhz, and DC 200mhz)
Mini disks that can hold more data then GCN mini-dvd's (1.8gb vs 1.5gb)
33 Million polygons per sec (compared to PS2's 20/m)
playback of ATRAC3 plus, AAC, and mp3 formats, as well as 3D and 7.1 channel sterio sound.
USB 2.0 port
backlit screen with a 16:9 aspect ratio
Wireless online play
by themselfs some of these things don't seam too unlikly to be put into a next-gen portable system, but not all of them. On the off chance that Sony can include all of this in a 'portable' package, the cost would be insane (think upwords of $300 or $400), and even then, actualy getting such a system to have a decent ammount of playtime would be quite difficult without including a very large, very heavy, laptop-like battery pack.
