Yeah, I did get the Ultimate Edition. I bought the original game, but then when I saw the DLC start to come out I realized what they were going to do so I returned it and waited, biding my time...
It worked! Did the same thing with Fallout 3 GOTY. I'm hoping I have some opportunity to do it with Mass Effect 2 before 3 comes out, 'cause some of that DLC sounds really cool.
