I don't know about that, besides every other dev that makes a LOTR game doesn't execute.
Most of the Lord of the Rings games that have come out have been pretty mediocre. I still liked the Battle of Middle Earth games though.
If Bioware did a LotR game they would ruin the lore even more. You'd probably play through a loose adaptation of Frodo's quest, with the added "feature" of being able to bang every male/female member of the cast.
I'm getting a bit exasperated with everyone assuming that the only thing Bioware puts in their games are six scenes. The two Bioware games I have played have had stronger stories, more interesting lore, deeper worlds, more realistic characters that you care about and the best dialogue I have ever experienced in any game and in most movies. I'm not saying Bioware is the best choice, I'm just saying they would do a much better job then Bethesda.
