As of now there are no PC games that are sold on Blu-ray discs, in part because most computers made today don't even have Blu-ray drives. When PC games start being sold on Blu-ray discs, there will most likely be DVD versions being sold concurrently, as it was when DVD-ROM drives first started appearing.
