I thought I'd post this because it wasn't mentioned in the news blurb on XBA's main page... there's a reason Dave Mirra was dropped from the BMX XXX game, and it had nothing to do with Dave Mirra.
Acclaim wanted complete control over making the game as "Mature" as possible, so they dropped all the pro riders and all the product endorsements. They wanted to make BMX XXX the most risque game ever made, and they didn't want to create the potential for tarnishing the images of the pro riders and products. This is why there will be a BMX XXX and a Dave Mirra 3... basically, the best of both worlds. Those who like pure BMX can get Dave Mirra (which will have all the pros and the obligatory product placements) and those who want XXX can have the guarantee that it will push the censors to the limits like no other console game in history.
