A demo for NCAA 07 is now available on the Xbox Live Marketplace.  NCAA 07 hits store shelves on July 18th.  The demo allows you to play as Florida or Florida State and weighs in at 1.05 GB.  Unfortunately in their desire to lock down the demo EA has limited the quarter length to 1 minute.  This setting limits you to roughly 1 set of downs per quarter with a large disruption in play at halftime.  I was excited for NCAA 07 but if the final product looks and feels like the demo, it will be a long wait for a decent football game on the Xbox 360.
