A new “Erebus” platform has popped up in the latest release of Unreal Engine 4 which could very well be Sony’s next console – the Playstation 5.
Erebus was found as a new platform in the engine’s supported platform list:

As you can see in the screenshot below the platform has a “TST2” abbreviation, probably to hide it from sneaky tinkerers looking where they shouldn’t.
Erebus is also being used alongside PS4 and Xbox One as seen in the code in the screenshot below.
The page shows the engine checking if the game supports crossplay, so you can come to a conclusion about this Erebus system being potentially able to crossplay with the current generation consoles.

The image above also shows the tag “bPS4SeenOtherConsole”, suggesting Erebus to be an actual console.
Now lets get down to why this could be the PS4, the first hint is the name. Lets check the Wikipedia description:
