Stating facts:
Android@HOME presentation – Google I/O 2011
Nexus Q announcement – Google I/O 2012
Nexus Q has a Texas Instruments chipset similar to the TI OMAP4460 in the Galaxy Nexus
Texas Instruments has ZigBee products 
Connecting the dots:
Buzz on the streets is that the announced Nexus Q might be ZigBee enabled. Good for us home-automation geeks! Too bad one of the dots did not leave a trace to Sigma Designs, making it it magically z-wave compatible. Would that be too much?
Dream on :-) ?
