I doubt that they have any plans to release their own laptops. The prototypes are to have something to test first-silicon with.
Those are likely not 'prototypes' for very early testing. Those are likely 'reference designs'. Intel and AMD have reference logicboard / laptop designs that system vendors can license , modify (e.g, put into a different enclosures), and sell. It is a completed system baseline benchmark platform. A large block of the PC market consists of designs not 100% designed from scratch for every single model.
Like AMD/Intel, Qualcomm is working with a couple of major laptop assembly vendors. Pretty sure there was a slide with either Quanta or Pegatron or some other major laptop actual manufacturer that is a 'partner' on this also. *(**) So the vendors get a laptop and Qualcomm basically says yours should basically work as good as 'this' (or better).
[ Similar thing happens for GPU reference cards. AMD/Intel laptops. etc. ]
Not sure why there is 'doubt' spinning about which vendors Qualcomm is working with. It was all included in the summit in Hawaii video ( Lenovo , HP , Microsoft , and others all getting copious stage time. )
Qualcomm wasn’t kidding about having many PC makers on board with its new powerhouse mobile processor, dubbed Oryon.

" .. The PC partners include Acer, Asus, Dell, HP, Lenovo, the Microsoft Surface brand, Samsung, and Xiaomi. Honor, a phone maker, also appeared at the Qualcomm Technology Summit here in Maui to announce its entry into the PC space — though as a Chinese phone maker, it doesn’t seem likely that they’ll ship PCs into the U.S. market. ...

The number is surprising, because only three PC makers (Lenovo, Microsoft, and HP) have committed to supporting Snapdragon before for Windows on Arm PCs, through multiple generations. The others have not... "
Qualcomm has attracted a relatively massive number of PC makers who apparently will design laptops around its Snapdragon X Elite PC platform -- and games are part of the mix.

With that many vendors Qualcomm will attract at least one of the major laptop makers ( most folks don't make their won. Apple certainly doesn't. )
(**) Found it. ODM Quanta , Compal, and Winstrom ( at approximately 1:15 )
Multiple UEFI vendors. Multiple USB vendors , etc. Not the number you would line up for 1-2 OEMs for 2-4 laptops designs. There is basically a larger foudational ecosystem of multiple suppliers here that need to put a foundation on. Qualcomm ordering up large orders of reference designs and having a substantially large number of internal folks using them, 'eating their own dogfood' , is a pretty good way of getting a solid, stable ecosystem released later.
Part of the delay between the summit (and those demos ) and 'release/ship' in mid '24 is the logistics of getting those large numbers of subcomponent vendors all lined up with more than a couple ODMs and more than several OEMs.
[ If Intel badly fumbles Meteor Lake (and Lunar Lake) then they are in deep doo-doo. Similar with wide rash of AMD APUs for 2024. ]
