Dear Sonos Product Managers and Upper Management,
You’ve successfully added me as a new convert to your ecosystem thanks to the Arc and you’ve gotten a decent chunk of change out of me already for the Arc plus a Sub 3 plus 2 One SLs plus a couple of wall mounts. I’m super happy with it all because it sounds great, was easy to set up, and because I didn’t have to run even an inch of speaker wire.
Now, want to sell me some more speakers? Update the Arc firmware to support a 7.1.2 system. You’re already decoding Dolby Digital Plus (which supports 7.1 channels) and processing Atmos on the Arc, so is it that big of a deal to add a couple of extra channels to the network? Or how about that extra RAM and processing power in the Sub 3? It can’t be doing that much right now - put it to use. And since the Arc doesn’t have to support the physical amplification of the additional surrounds, it should be a snap! 
Of course, I’m sure this is either MUCH more complicated than I’m making it (in that some Sonos audio / DSP engineer somewhere is rolling on the floor laughing his/her ass off reading this), or is already on your product roadmap. Or maybe it’s set for Arc 2 down the line.
But looking at my room, I can find space and power for an additional 2 surrounds and I’ll bet many of your Arc customers feel the same and would love to really take the Arc system to the next level.
So what do you say, Sonos? Want to take some more of my money? 
Love, always,
Highfalutintodd
wallet is safe until then.
