I think EA explains what Damon and I will be doing perfectly:

Game Changers are independent community members who are offered a close connection with people at EA SPORTS. To acknowledge Game Changers' leadership and provide a platform to help support their efforts, EA SPORTS often gives Game Changers early access to EA SPORTS games, as well as the opportunity to pass on their highly targeted feedback and recommendations about product design, development, and support.

Along with that statement both Damon and I have our own blogs which will be featured on the inside ea blog!
