In the interview with angry joe one of those guys say that you can go trough the game with a katana if you want ,slashing away.
It does not need to be a shooter if you do not like that playstyle and i kinda agree on why they chose to make it first person although an option to change it to third person would be nice but a ton more work to do both in a good way.
Also Cdprojektred is one of the few studios that gets my trust on delivering good games, we will see how that works out. :p
