Jason Holtman, once high up business guy at Valve, has left Microsoft. There, he was in charge of PC gaming.
Neowin spotted an update on Holtman's LinkedIn page which shows he left Microsoft in January this year, just six months after he joined the company. There he was in charge of Microsoft's PC gaming and entertainment strategy.
When he joined Microsoft he told GamesIndustry International: "Yes, I have joined Microsoft where I will be focusing on making Windows a great platform for gaming and interactive entertainment.
"I think there is a lot of opportunity for Microsoft to deliver the games and entertainment customers want and to work with developers to make that happen, so I'm excited to be here."
In a statement Microsoft confirmed the shock departure. "We can confirm that Jason has left Microsoft and we're grateful for his time at the company. We wish him the best in his future endeavours." Holtman has yet to reveal the reason for his exit.
What now for Microsoft and PC gaming? With Games for Windows Live set to be discontinued this summer, the future is unclear.
In a recent interview with Rock, Paper Shotgun Microsoft Studios creative chief Ken Lobb said: "We're getting very strong support internally. So we're really going after PC."
