I contacted Meridian last night and the SE won't start shipping till April so they can't really change my speaker. Besides I have suspicion that it is already on its flight to Australia. There will be more information after the CES, and an interesting quote from them:

"Being a Meridian product you will not be left behind in the update and upgrade space"
