Only those that really suffered from the limitations of the last gen consoles.
Skyrim could see huge improvements (especially the PS3 version...).
Mass Effect 1 also didn't run that well.
Maybe a port of Gears of War 1 and 2 using the either newest UE3 version (comparable to GeoW3) or UE4.
another chance for Team Fortress 2 on consoles
can't think of much else
