One thing I would like to see is a SONOS wireless 2 ch. amplifier. Using the PLAY:3 as surround speakers is fine if you have a place and a plug where you need them to go. If not, then what? Having a SONOS amplifier that can go anywhere and connect to standard speakers would be bada$$.

I've wall mounted a couple pairs of Play3's and it's a big pain in the ass. If you buy short power cords and place the power outlet just right you can pretty much hide the power outlet in many instances. That being said, some brain damaged individual put the mounting threads off-center which makes if even harder to mount horizontally - granted, they were making room for the back firing driver....
