It's kind of a biggie when your system dies a few days before a major release, and you have to wiat to play it a few weeks because microsoft screwed up. until they actually FIX the problem on systems they are sending out to stores (they havent yet), it's not really safe to get one.
This is why at almost the 0 hour I chose to buy it on PS3. I want to play online with you guys, big time, but I do get into the single-player a lot on GTA games, and I don't want to lose weeks and weeks of work if my 360 RRODs.
If you ring out you don’t send back your hard drive, so at the worst things are delayed but you don’t loose anything.
