IGN is having a convention on Oct. 22 and 23, like a "mini-E3." They are saying that Nintendo is on board for this convention as well.
My Theory-
Nintendo said they would release info about the DS Wi-Fi option and more REV info in October, so this convention looks like it would be a great time for Nintendo. I think Nintendo might release the finally specs here. I also hope that they show some games for the REV, as well as how the controller will work with new games. (Maybe then people will understand what the controller is capable of).
At last, another person who doesn't hate Nintendo! But yeah, the controller has a lot of potential. I'm excited to see how the games will turn out and how the controller is used.
