I love how I mention Xbox consoles multiple times in my post and you try to come at me with PC bull-ish. Pay attention next time.
If your suggestion is that they remake Morrowind and only release it on the 360, then that's just silly and not something Bethesda would do. They would obviously put it on the PS3 and PC, too. However, revisiting old games is not something Bethesda has ever done and probably something they'll never do again. They, wisely, want to spend time on
new content, as they should, because the old content is fine. Part of Morrowind's charm is its graphics. (Additionally, I don't care what anyone says, modded Morrowind still doesn't look so amazing. There's a reason all you ever see in videos are wilderness and stuff, because NPCs still look dated as hell and there's not much to be done about that.)
