I just got it on Monday myself. It's pretty fun, but nothing really mind blowing. Some characters are real assholes, and I can't bring myself to like the whole anime jokes anymore - some people are really into that shit, and I don't get how they can even watch it without getting embarrassed. It's like, a step above toilet humor and penis jokes.
Anyway, Sony never pays for exclusives; it's why Symphonia and Vesperia PS2/3 never came here, Nintendo/MS shelled out, Sony did not. Eternal Sonata was just a fluke in that regard.
