Wait wait wait, where did that info come from in the OP? I don't see it on the youtube video or on cdprojekt's site/twitter.
I Hope that's not true, from the start they talked about making your own character, it would really really suck if you were forced into a set protag for this game, Cyberpunk should be like Vampire: TMB where you get to make your own character and choose the class and how you want to play within that world. There's so many different WILDLY different classes in Cyberpunk that it would suck to be stuck to a generic set protag.
