yea i think sony is gonna pull a psp 1.5 ala DSi to reboot the platform a bit for those who still have psp-1000's or those who havent bought one yet.

this will allow them to cut some features and add others while still using the same tech in terms of game development.

at that point there would be no denying the strength of the psp brand and would allow them to drop a new psp2 in 2010/11

psp is only just about to turn 4 years old, i think they will want it to be 5 or 6 yrs old b4 they release psp2

they may bring out a version with Go! and camera built in, but will still be psp 1, using umd and have only 1 analouge.

i think psp2 will have 2 analogues
no umd
use some form of flash cards
have some built in flash for game downloads
built in camera
touch screen -maybe

I still say 2010. Only E3 2009 will reveal the true date. If PSP 2 is there or mentioned there then its likely to have 2010 release if not then its likely to have 2011 release.

you know what my psp is getting more love now too. I dont know why but i suddenly have found myself playing it more and more in between playing my consoles.

we wont see the ps4 till at least 2015 id say
