Two new demos became available overnight on the Xbox 360 Marketplace.
All-Pro Football 2K8: The demo presents a single five minute quarter between the Firebirds and the Cobras. Rosters are pre-set for those teams so there is no choosing of legends. Unfortunately this demo comes about 2 weeks too late. Better late than never though.
Nascar 08: The demo features an 8 lap night race at Daytona with the choice of drivers being Tony Stewart, Denny Hamlin, or JJ Yeley. The game releases and is in stores today.
