Style over all doesn't mean style over realism. That's a very unusual thing to say. This is set in a futuristic version of our world. Combat is deadly, and based on real-life ballistics and crime records. Nobody is black and white (not race), people all have real motivations for the decisions they make. They struggle with real problems that we struggle with today.
There's no magic, and people aren't going to be using their mind powers to hover around and shoot lightning out of their hands. This is a gritty, believable universe, but that doesn't mean there's never any room for lightheartedness or humor (there certainly will be, it's a CDPR game and they always do that well).
So... yeah. It'll be a realistic game. Not sure there was ever any doubt about that. CDPR has said as much on multiple occasions, and Mike Pondsmith's Cyberpunk -- while it emphasizes the "punk" -- is not a cartoony adventure with laughs, smiles and tickles.
I have no clue what sort of "RPGs" you've been playing.
You really think merely having a choice in how you resolve situations is all that's necessary for a game to be and RPG?
By your definition chess is an RPG.
At it's heart an RPG is the player controlling a person (robot, ameba, whatever) with traits, skills, and usually a personality that are not the same as those of the player. The player then uses the characters abilities (and hopefully personality traits) to resolve situations. No First Person Shooter can EVER be a "true" RPG simply because they use the players ability to put a crosshair on a target and trigger an attack. The characters skills (or lack thereof) is not a factor.
I think he doesn't understand what you're saying, is all. A game can be an RPG with FPS-style combat (again, a game fits into a genre based on a sum total of its parts, you can't just point to one mechanic and say "its XYZ," not unless it completely dominates the game), which I don't think you're arguing against.
We already know 2077 will have many more elements of an RPG than just choice.
