Star Scream on 26 February 2009
Sony just announced a ton of new games, and there are allegedly some big PSP games still unannounced - Jak and Daxter, Gran Turismo, Killzone Liberation 2 (confirmed in the latest UP mag).
Also, PSP has a huge list of announced games for Japan as well, including the brand new Monster Hunter Capcom announced in new Famitsu.
Somehow I don't think we'll see the real successor before 2011 - at the earliest.
