Well, OK, they’re calling it the Vorkosigan Saga Sourcebook and Roleplaying Game for GURPS Fourth Edition (official webpage here), but a lot of us in the gaming community have been waiting for this supplement for an appreciable fraction of a decade now. Still only in electronic form for right now, but I can hold out for the print version. I sort of have to: that’s half a month’s ‘pay’ for me.
If you’re wondering what a ‘Vorkosigan’ is… well. Start here and work your way through; there’s some background on Lois Masters Bujold here. Nobody will judge you for your lack, I swear.
