cogadh: Infrogrames bought everything that was Atari (much more than just a shell), so for all intents and purposes, Atari became Infogrames, then Infogrames changed its name to Atari.
Not quite true. In fact, if you're after the old Atari, then Midway was the company to look for, as they ended up buying Atari's arcade division. Atari Games was renamed Midway Games West, and when they were shut down (years ago) there was virtually nothing left of the old Atari.
But this doesn't really matter. From a PC standpoint, it's Infogrames and Microprose that's interesting. Not the old Atari IPs.
And at any rate, I don't agree that Atari is more likely than any other big publisher. People are largely taking things for granted that they don't know. Activision has been making PC games since the early eighties, obviously there's tons of stuff there that they'd love to sell for $9.99 or even $5.99. Infocom, anyone? Same with EA. The only publisher we know has gone for a "nothing less than $9.99"-attitude is Ubisoft, and they _are_ here.
