Bleh, I do not like the idea of two discs. I can accept it to an extent, three is stretching it, and four is just too crazy. But this answer deserves some merit on it's own;

And why on Earth would BioWare need two DVDs - that's over nine gigabytes of capacity - for one single game? "Because you cannot fit this much awesomeness on one disc," Priestly said.
So I'll forgive Bioware.
Still, I don't like the idea of having two disks, even if you only change it once. I don't get the excuse of "There's so much sturf in it!", is it that hard to compress a little bit of data? And if I can play devil's advocate for a bit, that excuse just seems more pompous and self-entitled than an actual reason to have two discs. But hell, maybe they do have enough game to warrant 2 discs, can't know for sure until it's released.
Then again, I don't have an Xbox or a PC good enough to handle any type of games, so my little peeve is negligible for most people.
