q about xbl, do they keep all the demos = dlc and stuff on their servers forever

Hi, I'm soon to be getting a 360 and hav 1 quick question about xbox live, do they keep all the dmos and dlc on their servers forever so that late-comers like me can download tham?

Thanks in adbvance...

that's not true.. most stay up on the marketplace, but i have noticed some demo's are gone. (i noticed tony hawks p8 is gone, along with battlefield)

So far I haven't seen any of the demos taken down off their servers, but I would assume they would have a few yeas though.

btw... It's not a big deal if they do. I play a demo once (if it's crap) and delete of my hard drive, never to be downloaded again. The GOOD demos, like BlackSite, I'll play over-and-over again until I get the actual game, then delete it from my hardrive, never to be downloaded again.

Either way, a demo typically hasa shelf life of a month or two on my hardrive.

The GOOD demos, like BlackSite,

Blacksite? That 3 minutes of gameplay is considered good?!
