From an interview at Next-Gen.biz this morning (my emphasis):
[GameTap general manager Stu] Snyder also says that GameTap would be moving its TV programming from its client to the web, as well as launching a digital retail store where users will be able to buy and download new and cataloged games for keeps.That's quite possibly the best thing I've heard about GameTap in a while. If the downloads are untethered -- i.e. don't require a network connection to run and can be archived and reinstalled later without communicating with GameTap -- then I'll be really impressed. I doubt it will be as nice as downloading legal ROMs from StarROMs, data that could be used on any system with any suitable emulator. We'll see.
If anyone from Turner is reading, how about letting us in on some details of the new sales model? I'd be really interested to see what GameTap will offer that is different from what Steam and other download services are doing. Use the Contact Us link at the top of the right sidebar.
GameDaily has some other interesting data about GameTap. In particular, they say that membership is up almost 300% over 2006. I will try to go back and see if there was any information in 2006 about how many subscribers they had.
Also, they appear to be offering Tomb Raider Anniversary for on-demand play the day it launches through the GameTap subscriber service. You might recall that TRA was already coming to Steam (although it isn't clear if it's coming at launch). Certainly it's not new to see the same game on different services -- practically every one out there has a licensed version of Pac-Man -- but it is unique for the same, brand new game to show up on more than one service on launch day. Very interesting.
I think you missed the big thing, tomb raider anniversary is going into their SUBSCRIPTION same day as retail, not their store!
