Thanks to Game Informer for releasing the screenshots. We see Shepard fighting some Cerebrus squads so it's clear they want him dead.
Don't expect a huge difference in graphics though. With around 1 year of development time, the graphics should be similar. Bioware also mentioned that the PS3 version of Mass Effect 2 is using the engine used for Mass Effect 3. A lot of changes were already mentioned and i can't wait to see Mass Effect 3 in action.
