The Obsidian Forums have posts from Obsidian's Matthew Rorie to tidbits in the leaked SCEA documents (thanks Shacknews), this one in particular responds to allegations that Alpha Protocol is not enough of an RPG:

And yes, I believe the gentleman in the quotes works for SCEA. As for what he said, obviously we enjoy any feedback that we can get, but without knowing how much of the game he played (and I seriously doubt that someone as busy as a product evaluator for Sony is going to be playing through an entire game if it's as long as Alpha Protocol), it's hard to judge what he meant by those comments. Suffice to say that Alpha Protocol is going to tickle your RPG tastebuds when it's released.
