These are for the PSP, though. Sony is desperate for games that sell well and Tales of has a pretty dedicated fanbase. I can't think of a single reason these wouldn't come here.
Actually these games were released before, they were for the PS2. (Except ToD for the PS2, that was released just near the end of 2006.) But ToD2, and ToR were for PS2, and now they're releasin' em' for the PSP.
Down with DS! Do a lil' bit of research on wiki or somethin' and you'll know. Lots of people were disapointed when ToR didn't come out, it was originally supposed to come state side in 2002(i think) but due to the Anti-2D policy the game was cancelled, what a shame because Tales of Rebirth looked pretty tight, so youre best bet would be to import it.
But as you said, the fan base has been increasing, so the chances of it being released stateside is possible, but I highly doubt it, I had my hopes for ToD for the PS2, but it didn't come to happen, so I just gave up.
