I don’t think Sony cares that much about indie developers.
But that does not mean indie developers can’t release games on the playstation store.
There are thousands of games being release on playstation store every week/month.
This is not about Sony, is about Crate.
I think there is a big console market for ARPGs.
Porting the Xbox version to PS5 is probably much easier then the work required from porting it from PC to Xbox.
Still is a matter of Crate even wants to do it anyway.
No. PS5 (and all others) has it’s own graphics API. Xbox has some version of DirectX, which is also what’s used for the PC version. Also Xbox runs some flavour of windows, PS runs ‘linux’.
It’s probably the hardest console to port games to if you’re not already familiar with it. (There’s companies that specialize in this kind of thing)
