Although the list of trophies for the Omega pack are not yet made available, according to a poster at the PStrophies site they asked at the blog and were told that there will be One Platinum, and the rest of the trophies will be made up of different achievements over the three games.

I'm kind of expecting them to make the trophy list longer, with lots of easily achieved Bronze trophies, and remove what are considered the hardest ones like Zone Zeus , Beat Zico, Airbraker etc...maybe replace them with more Online orientated trophies, like get a certain amount of online Medals, or a certain group of 5 or 10 of them.....stuff like that
