Last week, Valve founder Gabe Newell caused quite a stir when he claimed that Windows 8 was "kind of a catastrophe for everybody in the PC space".

“I think that we’re going to lose some of the top-tier PC [original equipment manufacturers]. They’ll exit the market. I think margins are going to be destroyed for a bunch of people," he said.

“If that’s true, it’s going to be a good idea to have alternatives to hedge against that eventuality. But when you start thinking about a platform, you have to address it."

Now it seems that at least one other developer agrees.

Rob Pardo, executive vice president of game design at Blizzard, took to Twitter to endorse Newell's comment.

“Nice interview with Gabe Newell – ‘I think Windows 8 is a catastrophe for everyone in the PC space’ - not awesome for Blizzard either” read his tweet.

The big concern seems to be that Microsoft will make Windows 8 a closed system, and in doing so will seek more control over various applications as well as purchases made through Windows.

Microsoft is yet to announce full details of its upcoming OS, which is scheduled to launch on October 26.
