BioWare is busy showcasing Mass Effect 3 and their Dragon Age II: Legacy DLC at this weekend's San Diego Comic-Con, and since they know many of us can't be there firsthand, they're hosting live demonstrations on BioWare TV. Furthermore, if you have a question about either title, you can tweet it to @dragonage or @masseffect and either Mark Darrah (Legacy) or Casey Hudson (ME3) will answer it during their respective demonstrations.
