I can personally imagine a better screen, speakers, controls, ergonomics, cooling, another USB C port, slimmer and lighter, etc.
I know that most of these things are already good, but they can always be improved. We’ve already seen other handheld PCs do some things better so I imagine Valve can improve as well
This is just my theory, but with the price of game development increasing so rapidly, I think it’s getting harder for the impatient to cover the development costs and make a profit off shitty games, unless the game has a huge following. Games like COD, Diablo, Star Wars, etc.
For games without that following, I think they are definitely being punished for their bad practices. Like Gotham Knights, Red Fall, Saints Row, etc. Games that cost so much that they have potential to shut down studios
