The NCAA Football 12 demo is now available for the Xbox 360 (can be queued up from here) and will be arriving for the PS3 when the store update takes place in the late afternoon/early evening. The download is a massive 2GB.
The demo features two separate matchups (Alabama at Florida State and Oregon at Texas) and allows for the unlocking of five different Nike Pro Combat jerseys for use with retail copies. There is also expected to be at least one “Tuner Update” created based on feedback to the demo that will influence the game prior to it officially releasing.
