JR posted a blog about the game which has since been removed, in which he mentioned some details about his involvement in the game:
"It looks like WWE has lined up a really cool, THQ video game for me to work on and that I will likely be broadcasting alongside the King in the game where Legends compete with active Superstars.
"I'm not sure of the release date or the creative details, etc but the concept, as explained to me, was really cool. I hope to begin my voice overs in the next week or two. We're burning daylight on this one and need to get rocking. I'm ready!"
Sounds good to me.
