I’m lucky because I have a girlfriend who wants to buy me a steamdeck. I have a gaming PC already but I am away for a while due to grad studies. I’m worried that we buy one then a new version comes out in a few months. Should I buy one later this year?
Valve has said they are not planning on an update anytime soon so I wouldn't worry about it. If you have a good gaming PC, you can stream games to the Steamdeck for even better gaming!
Valve have made it clear they won't be releasing a new version any time soon. It's your personal choice, can you afford it? Do you want to spend the money?
I think it's brilliant, but I know others who'd prefer a normal console.
There is also a program that lets you stream Playstation games to the Steam Deck, though I'm not sure if it's local-only (many of the ones for PCs, you can play games streamed from your PC from miles away if you have decent internet in both places).
I get wanting to spend money wisely... but if you do it too "wisely" your gonna miss out on a lot of fun... do you friend... as far as I know nothing is in the works nor will be for a long while
