Thanks for the clarification Ian, the picture made it look like a larger unit.
If I didn't already have a Sonos investment, I'd certainly be interested. I like the fact that with Axiom proposed solution, the speaker lineup would certainly be better than the Play:1:3:5.
However, if you could jump the queue and offer a Sonos Connect like device with HDMI input, a Dolby/DTS codec module, and pairing capabilities for 5.1, 7.1, and even 5.2.2... so I could stream Netflix/Amazon and allowing me to ditch a receiver and DVD/BluRay player... I'd seriously consider that. I suspect this would also be popular amongst the condo/apartment crowd where space is a premium and ability to setup a surround sound home theater is difficult seeing they can't run speaker wires through walls.
