I think I read earlier that the Home interrogation is you (I don't know if they mean the player of the character) can sit in a room and talk strategies and stuff before playing.
Maybe I am confused with something else.
Will try to find the article and edit later.
EDIT - Here is the IGN article on the new patch, the bit about home is after the first picture I think.
IGN: Warhawk v1.3 Detailed
Reading it again, it looks like it was actually talking about PS Home and not just an in-game feature, I read it wrong the first time. I though it was an apartment in the game, I enver even thought it could be
the home. I hope they bring Home out soon, I think I will be using that more than any game (except GTA4).
