shio is indeed using a blanket statement, having absolutely no facts to back up any DD sales claim he's making.
That's why I, and others at VGC (along with other DD leaders) are looking into exploring ways of aggregating Steam's sales numbers, in hopes of finding out how well they are.
If you want to use 18-24k concurrent users as being a massive number of units, projecting to millions of sales, I must ask what you think of Halo 3 and other games having 5x that many concurrent users at any given time.
Furthermore, what about all the 'other' non-Valve games on Steam that are reporting a few dozen, or hundred users at any given time like your much-touted AudioSurf? Wouldn't that equal out to just above 10,000 sales for such a game? If so, then I guess Steam is an utter failure at the DD model for anyone but themselves.
Back from the dead, I'm afraid.
