I really don't see why first person is a problem. I play lots of first person games mixed with third person games, and I never felt one type is preferable above another. I feel very comfortable with both.
Whatever you think about it, I have played lots of hours in "Elder Scrolls" games, and these games where first person with third person cut-scenes. So character creation still is very important. Also - I think sneaking (line of sight) and targeting is way more easy when in a first person perspective. So yeah... I don't mind Cyberpunk is first person perspective.
This is, of course, a personal opinion.
