Qualcomm and Google talked about it during the Snapdragon Summit.
During Qualcomm’s Snapdragon Summit, Google's Rick Osterloh discusses next steps for a desktop version of Android.

calling this "Android PC" is a bit dubious.
" ... “We're basically taking the ChromeOS experience, and we're re-baselining the technology underneath it on Android,” he said. “That combination is something we're super excited about for next year.” ..."
From the end user side it is more so ChromeOS. Just will likely be able to run Andriod apps on 'side' without using as heavy a virtual machine. However, a decent chance the boot security and basic experience will be quite ChromeOS like. If there is 'headless' AI/ML subsystems don't have to re-invent wheel in that part of core OS library foundation also.
It really made little sense why ChromeOS and Android would run every diverging Linux kernels over the very long term anyway. It is a bit like how Apple converged the filesystem into. APFS that is used on both iOS/iPadOS/macOS etc into a easier to maintain source base. Apple has layered various tweaks to same central macH base over time.
The core of the Android user level ecosystem never really did all that well adapting to Tablets ; never mind classic PC screen form factors. ChromeOS hasn't had that problem. Tablets have been the "happen to work good enough" stage for a long time.
I kind of suspect this is one of those. "King is dead , long live the King" situations where "Android PC" is s "Prince of Wales" temporary tag until the classic ChromeOS gets killed off.
It will be substantively much more easier to move the ChromeOS ecosystem off of being predominately x86 over to being predominately being on ARM once have a more solid hardware infrastructure foundation. Google could even move it to their own custom hardware if they wanted longer term once the volume is large enough not to severely disrupt their partners. (e.g., when custom phone chip gets to gen 4-5 then make a bigger die version if there is still slower than desired uptake by market. ) .
Is that going to be a "Windows killer"? Probably not any more than macOS is.
I think Qualcomm's excitement is that their AI/ML work on phones will more seemlessly translate over to 'new' CHromeOS/Andriod PC and coming off of the smartphone ecosystem they have deeper leverage over competitors. (closer matching to what Gemini does on Pexel phones with Qualcomm phones. )
P.S. Maybe the userland experience will change so much they'll think that renmaing it would be better "Android PC". I think that is going to be a lot more goofy than it was to slap. Android on 'TV' to get to Android TV. they have a base in ChromeOS. just like classic Mac OS was a base for MacOS X. However, Google has made really silly product moves before. So could that be their path.
And a bit of an issue is that ChromeOS still has deep implication that it is just a big Chrome Browser. But slapping "Android" on it isn't much of an improvement (which has its own phone implications )
