The only improved functionality I can tell is support for AirPlay, otherwise it's basically identical except for the 12V trigger and another $50 of price on top of what was already their most overpriced product. No Bluetooth and no room correction and more money makes this a bit insulting. Except for the RCA jacks the components [network stack, decoder, DAC] to output audio are built into their $99 Ikea speaker. Their product line is dying for a $200 or cheaper just decoder, no inputs, no controls but they won't make it because it would probably suck the air out of their custom install market.
As far as high resolution support there's no mention of it and if my understanding of their network structure is accurate it's not coming any time soon. They've put a ton of time and energy making sure every product they make is compatible with everything all the way back to their original ZP100. Support for high resolution would mean some Sonos could support it and others couldn't which would impact grouping, zones and other usability concerns which would be very off brand for a company that's put some much time and energy into ease of use. That said they could at least support high res files downsampled to 16/44 if they're not willing to do full support. There's also the fact that years (decades?) into high resolution audio there's still no actual evidence that sampling above Nyquist for 20,000 hertz (44.1kHz) meaningfully improves audio quality.
In my case I'm not so invested in Sonos (just 2 Play:1s and a Connect) that the instant an alternative shows up I won't jump ship. My living room receiver supports Airplay natively and really the only thing keeping me in this ecosystem is reliable sleep timers and alarms which for some reason has eluded Bluesound, Apple, Denon, Yamaha, Play Fi and a host of other wireless systems. At least the pricing on the Port won't crush used Connect pricing.
