Microsoft's Xbox 360 recently had some troubles that caused retail discs to not work in some Xbox 360s and Sony's recent update seems to be causing overheating for people's consoles. Sony is, of course, having the worst time of all (because they're having way more troubles, like with their network, the natural disasters, etc...), but it's surprising to see 360 have an error like this at the same time.
I guess just don't update your systems for a while, until they've patched out these strange errors; Microsoft says to contact them if your 360 doesn't read discs after the update.
