We're not really sure. It's "reading the tea leaves" at this point. I doubt the speakers will have acoustic lenses, based both on the price-point and the fact that it is going to be a stereo speaker. I personally hope we never see a single speaker with two lenses popping out of it!
We know it will not have a full BeoSystem 3, but it will have a surround sound module and code converter with connectivity closer to the BeoSystem 3 (if not identical) than the BeoVision 8. It is also expected to be the first in our new digital television platform which will creep into the lineup in the coming few years.
As for a stand option, the only thing we know for certain is that it will mount on the wall "right out of the box" so it seems like that will be the preferred option if not the only one. Anything more would simply be speculation.
I think we'll know exactly what we're dealing with by late summer and should all have on in our homes by November! 
There is scarcely anything in this world that some man cannot make a little worse and sell a little more cheaply. The person who buys on price alone is this man's lawful prey. - John Ruskin
