Also, game demos usually have a tendency to be more "alpha"-versions of the finalize product - in other words, I doubt Irrational decided to make the demo on august 8th and release it on August 13th, so they probably made the demo out of a build they made, say, in February or March, which means that the final product will more-than-likely look better/different.
I would strongly disagree with pretty much that whole paragraph.
The demo is almost certainly created from a near final build of the game by removing all the art/sound/code assets not needed by the demo. It's a chunk of the whole, not an early version of the whole. A developer would never release a demo of their soon-to-be-released blockbuster that lacked all the bug squashing, graphical improvements, and general polish that they had done in the past seven months. The final version that you'll buy in the store will likely be identical to this in every way except for the few ways that they changed it specifically for the demo.
The general public will almost never see a game in it's alpha stage. Especially since one of the definitions of an alpha release is that it's for internal testing.
