According to The Xbox 360 Uncloaked by Dean Takahashi Jon Kimmich also negotiated deals for Epic's Gears of War and a new Valve game for the Xbox 360, of which only Gears of War was signed by MGS.
Before joining Microsoft Games Studios, Kimmich held other positions at Microsoft, which included development manager for a new product development group in Microsoft's Hardware Team, responsible for hardware devices such as the original award-winning Microsoft Natural keyboard. The addition of the Windows-key and application-key, which first appeared on the Microsoft Natural Keyboard in 1994 (and are now standard on most keyboards and laptops designed to support Windows) has been attributed to Jon.
In June 2004, Jon Kimmich left Microsoft to become Producer and Director of Business Development for Day 1 Studios.[1] Since this time, Day 1 Studios has developed MechAssault 2, F.E.A.R. for the Xbox 360 and PlayStation 3, and Fracture.
Jon Kimmich was also an investor in WizKids, LLC, a game company founded by Jordan Weisman (founder of FASA Interactive) in 2000 to develop and sell a line of collectible miniatures.
