Bioware doesn't own the rights to Baldur's Gate 1 or 2.
More importantly, Bioware is gone and only exists in name anymore, and has been for a very long time now.
Bioware was sold to EA because the owners felt they really needed to make a MMORPG and they wouldnt have the necessary funding.
The original owners of Bioware are gone and Bioware is really just a label EA puts on everything they like to put the label on.
Also it turns out MMORPGs have been a fashion of sorts and its basically over. Some old dinos like WoW or Eve Online struggle on, but most gamers, especially younger ones, arent going for them.
And Biowares Star Wars: The Old Republic, the MMORPG they lost the company over, AFAIK still exists, but never was much of a success.
