During the stream in this clip at the end says “the free upgrade to the new generation of consoles will enable these features,” what does that mean? It reads like you have to pay for a next gen console to unlock the vertical split screen, that’s not what it means, right?
They said that the Vertical Splitscreen will be applied to the current gen.
I believe the 4-player split-screen and 60fps/4K will only be on the new hardware. The other reply is correct about the vertical option becoming available on the current gen console game versions.
My take is that the 4pl and vertical options will be automatically included with the next gen versions. Whereas vertical will need to be patched in on the current gen.
