Any idea of what sort of online capabilities the PSP will have? How will it connect to a network? Is there any chance that network gaming with the PSP will be compatable with PlayStation 2 and maybe even PlayStation 3?

PSP specs:

Input/Output

USB 2.0
Memory Stick
Extension Port (Reserved)
Stereo Head phone Out
Digital Keypad
Triangle, Circle, X, Square, L1, R1, Start, Select
One analog joystick

Communication

Wireless LAN(802.11) [Hotspots, Home Server, etc.]
IrDA [PSP, Mobile Phone, etc.]
USB 2.0 [PSP, PS2, PC, etc.]

If any of this has been announced before then I'm sorry. Looking at the forum, there isn't a topic for PSP Online, so I thought I'd make one anway for discussion.
