Companies tend to be very particular about outsourcing their code. Falcom wouldn't let XSEED touch their Ys code, I seem to remember reading somewhere.
So it's an issue of Baba's team not being big enough. Which I do kind of understand, actually.
As Nem & I were discussing in the Vita thread, though, Tales of Innocence R & Hearts R were developed by 7th Chord. Though I'm sure Namco has the code now, they had no problem outsourcing it to make the game - so they should have no problem outsourcing it for the translation.
I hope Sony comes in to sort out this mess, really, because it's pretty clear these games aren't going to come across by themselves.
