I'm surprised I haven't seen more talk about San Andreas on here lately. About two weeks ago, GameSpot and IGN released features on the game. It appears they got the info for their features from the same meeting with game execs. I also stumbled across this site, which (if believable) has a lot of cool info about the game. Grr, 10/26 will never get here.
I pre-ordered the game from BestBuy online (to get the Nariko costume) and got both the game and promo card in the mail on the 22nd. Both the promo and network stuff don't work yet though (come back as invalid or can't connect)
