[2023] Will the PS4 version of 7d2d ever be updated?

The existing console version unfortunately will never be updated. The publisher, Telltale Games, went under and one of their last-ditch get-out-of-bankruptcy-quick moves was to officially release the console version of the game in the hopes of getting a bit of extra cash inflow.

Unfortunately, it didn't help them- They still went bankrupt. And doubly unfortunately, Both the Microsoft Store and Sony Playstation store prohibit officially released games from releasing updates that would break save compatibility with any existing saves... And, most unfortunately, every major version of 7DTD since breaks save compatibility from the version before it.

So, they literally can't update the console version to the current version, the console store rules say no.. As such, they're focusing on a re-release that will be in-line with the PC version, but not likely to be available on PS4- Instead it'll likely be PS5/XBONE.

In the first Dev stream for Alpha 21, Rick and Joel showed A21 footage running on a PS5 to highlight the fact that they are developing the new console version concurrently with PC along with partner Titanium Games from Australia.

In a shocking announcement, Rick says that not only is the console development even with PC but that if all goes well their goal is to release PC Alpha 22 as the Version 1 release for console. Cross-platform play will come later.

So the old goal of waiting until PC goes gold before releasing console versions has been altered to getting 7 Days to Die out to consoles even before PC goes gold and to continue to finish up both PC and Console versions concurrently.

Rick also mentions that they are in talks with Microsoft and Sony to negotiate a discount program for existing owners of the original console game.

So, no, The new console version won't be available for A21. But hopefully will be for A22.
