EA and Criterion have announced Burnout Paradise as an upcoming addition to the PlayStation Network. 

Originally released in January 2008, the sixth Burnout title has been retail-only thus far, but will soon be available for download on PSN for $29.99 with all updates released thus far by Criterion already incorporated.  This decision falls in line with the "Year of Paradise," an initiative to evolve gaming with the regular release of DLC that pushes games beyond their original retail form.

Gamesutra quotes Criterion studio manager Fiona Sperry on what the developer hopes to accomplish:

"Our mission at Criterion is to provide the most entertaining gaming service possible. In order to do that, it's key that we have the ability to deliver content to players in ways that work for them - through quick and easy download or via traditional bricks and mortar."

The first update was free and made available through XBL and PSN earlier this month.  The download pack included three new modes, vehicles, and 70 challenges, and Criterion will soon be adding motorcycles and Trophy support in their upcoming update.
