XM-Sirius Merger is finalized as of today. As to the question of equipment compatibility, see the following:
In an interview with USA Today last year, Mel Karmazin, CEO of Sirius said this:
Q: You've been working since 2000 on a radio that can receive both XM and Sirius signals. When will that be completed?A: We have one. It's in my office. … At this point, there is no market for it because nobody is subsidizing the cost of the (dual) radio. Today what Sirius does is that we subsidize (our) receiver. And the reason we subsidize it is because we're gonna get a subscription. So, we think with the merger this really represents an opportunity for us to be able to financially subsidize radios that provide for interoperability.
