With Sony's recent CES presentation I like everyone else feel a little disappointed at the lack of any solid information on the PSP. If the rumours hold true that a US and European release are to be in March, I would have thought that they would let people know now what's going on, because to be honest March isn't that far away.
Maybe it's not a big deal with the PSP, localisation wise. They don't have to change the hardware at all, or any of the OS because it's already multilingual. The only thing that needs to be altered is the language in the PSP games, and maybe the manual for the unit itself. Maybe Sony don't need that long to get it ready for launch, and they'll let people know when they think it's nearly time.
One of the titles I'm most looking forward to on the PSP is GT4 Mobile, since there has been such little info on this title I really can't wait to see how it's going to turn out. Hopefully it will have some decent interaction with GT4, where unlocking something in one game opens up other items in the other.
