Valve and follow-ups are like oil and water, they just don't mix.

As much as we all love to meme about Valve's aversion to the number "3", the Steam maker has a penchant for leaving previous pieces of hardware and software to collect dust. But, it appears that Valve is trying to change that with the Steam Deck and the SteamOS.

As the company celebrates the launch of its portable PC in Asian territories, Valve revealed a glimpse into the future of the Steam Deck.

Here's an excerpt from the free ebook by Valve: [The Steam Deck] is a multi-generational product line. Valve will support Steam Deck and SteamOS well into the foreseeable future. We will learn from the Steam community about new uses for our hardware that we haven't thought of yet, and we will build new versions to be even more open and capable than the first version of Steam Deck has been. If that's not a confirmation of a Steam Deck 2 or 3, then we don't know what is.

The Steam Deck is arguably Valve's best-selling piece of hardware yet, which is why it's now a huge part of Valve's future unlike the Steam Controller, Steam Machine, Steam Link, or the Valve Index. Valve hasn't made the numbers public yet but the console ranks among top-sellers on Steam and has consistently sold out since it was first announced last year.
