Well they did mention that Catherine was still up in the air, but I agree - it's not out in Japan and not even worth mentioning quite yet.
I actually thought there were supposed to be better Tales games than those ones mentioned that never came over. Mind you, there's like a million of them altogether, so he's damned if he does and damned if he doesn't. :P
As for Growlanser PSP, it was a remake of the supposed 'best' Growlanser.. that might have something to do with it. Unless it was a shitty remake or something. But I guess it was more about the sales than how shitty or not that game was. And Atlus USA only has so many resources at a time. (ie. they were doing Persona, Strange Journey, all that other stuff that they knew would actually sell. :P)
