I do not believe there is a buy out as the Canadian Government already stated "not going to happen". So obviously they were approached about it. BUT, I do believe a Microsoft JV for the US only..... that just might be the reason for the one month US delay(maybe in Super Bowl Comm). I don't believe the carriers are still testing because they stated 3 weeks ago that they were approved. Also, I believe a Lenovo JV for China. Hang on boys this is the stock to own.
The other reason I believe something will be announced in the Super Bowl commercial is they never pre-released it or even a small trailer. Statics say if you pre-release the commercial you will get 600X more hits on youtube. They opted out not to get this extra publicity because the news would be out then. Be careful if you have a sell order for Monday, you may loose out. It's great to a RIMM long
