I would think so. Their APU can't keep up with the 7840U found in so many other handhelds now. Lots of people are going to the ROG Ally and Ayeneo options among others
At the moment, the Ally makes news about their bad build quality. I'm curious for how long the hype about that device will last, the Steam Deck still holds up so far.
(Edit: I'm talking about the Deck) I think it holds up because it's the most well known and the openness of the project allows for all types of addons which is awesome.
I would assume it will go on sale again as it is in valves interest to have more deck users. They can also use it to bump up sales if deck sales are slowing as people on the fence will be more likely to buy it at a discount.
