Based on other games, it's likely going to be two lists, and it's most likely gonna work like Motorstorm RC where you unlock the same trophies on both consoles.
I'm gonna play on both I think. Still don't know enough about the differences of each version if any of them have any advantages or disadvantages. I know one thing, and that is I really hope to hear more about this game soon. It's my most anticipated title this year.
Thanks to Sackboy_LBP for the awesome sig.
