You could called Mass Effect a TPS/RPG or action RPG, but it has a lot more going for it on the RPG front than BioShock 2; varied choices with varied, in-game consequences, separate side- and main-quests, dialogue system, non-combat skills, stats having more of an influence on combat.
I think I get your point, as far as critiquing seeing ME2 as the "next evolution in RPGs" goes, obviously both BioShock 2 and ME2 share that they're simply less RPG than the RPG of old. Is that an evolution? I wouldn't say so. Is it where mainstream "RPGs" are going? Sure.
