I'm going to stop you right there.
With all due respect, D&D is a combat engine.
That's why 95% of the rules revolve around combat, in every edition. That's why all the splatbooks are geared towards combat options. I do not believe there has ever been "1001 Outfits and Chamberpots to fill your castle" book.
D&D came out of chainmail, which was a wargame. It has, and unfortunately, always will be shootin' fireballs at orcs.
Regardless of how you play it, this is how it is treated by, I feel, the vast majority. People can put as much fancy decoration as they want, but the system's function is to facilitate combat.
WotC designed 4e by using market research, and gaming data. They did a lot of research on how people played the games. They designed 4e to cater to how people played D&D, rather than how "they should" or "they might". It's practical application of "What do most people do when they sit down in front of their character sheet across from the DM screen".
In my opinion, your playstyle doesn't really have anything to do with what edition, or even what system you're playing, because what you seem to care about is the story and the interaction of Character to NPC. So I don't think you should be concerned with what's in the Core 4e book or not, because it's not going to really be catering to your tastes in a game.
Of course it matters what edition I play. I've been playing D&D since over 15 years. When 3E came out, I switched after reading the PHB for 30 minutes - it was simply so much better than 2E for my playstyle for all the options it offered, and the flexibility. With 4E, the reaction wasn't the same, it feels more limiting for my playstyle.
So, regardless of what the majority does - for me, 3E catered to my playstyle. So far, 4E does not. Maybe once it has a bit more options than the PHB, and might introduce (more) rules that deal with non-combat stuff, it might fit my playstyle.
Until then, 4E feels incomplete to me, since it offers less than what 3E does, and - and this is important - les sof what I want out of a game.
