Corrine Yu,  Principal Engine Programmer for Halo 4 has changed her Linked In and Twitter accounts, indicating that she's now working for the PS4 console, as found by Pound_lb003 of NeoGAF.

According to Twitter, it appears that her new role will be largely to do with graphics coding for the console. In a tweet to a Naughty Dog dev, she notes that she's happy to have moved from Windows 8 coding to the PS4.

This move comes after more than five years working for Microsoft.
