The answer is yes. the PSP has no region locking, even though there might be some language issues, like if you buy a game in Japan or Spain, the language would be in Spanish or Japanese.
As far as the "amount of time left for games" I do not believe they would be releasing a PSP-3000 with only one year worth of games, also, the PSP is much more versatile, with Skype, GPS, camera, tv, internet, radio, mp3's, movies and RSS feeds. So carry on enjoying your PSP, and don't worry about regions. The first guy (whose answer was deleted) doesn't seem to know that the console wars occur on 2 fronts; home-based and handheld. PSP is a contender in the latest gen of handhelds, probably when Sony decides that they've milked enough out of it, they'll move on.
Yes.
I think those US PSP games are actually Japanese games translated to American English. And all PSPs are japanese, so it should work just fine.
Yes but if there is a game for Japaneses and English you can save Japaneses games with Englishes data,all PSP can play PSP game Englishes or Japanese.PSP games are region free, any PSP game will work on any PSP.

yes all psp games works on every psp

They only work on American Psp's because they are off the same region.
Yes, from experience i have played games on my PSP from China and Europe. The only differences between releases are (generally): art, language and rating system.
