We have just posted some info and screenshots for
NBA '06.
"Expanding upon the best-selling 5-on-5 basketball simulation on PSP, NBA '06 for PSP incorporates all-new game design, animations, and mini-games for gamers to play anytime, anywhere. Supporting up to two players via ad hoc or infrastructure mode, NBA ‘06 for PSP offers the chance to play any of the 41 authentic NBA teams, including six National Basketball Development League (NBDL) teams. Two new mini-games, HORSE and Dodgeball, allow players to step away from traditional 5-on-5 play and engage in some classic schoolyard battles."
