Seems to me like a strawman to be comparing the old BG games to something being made today. The more appropriate comparisons would be the RTwP combat of Pathfinder to the TB combat of BG3.
I am not sure what you mean by that - the biggest difference between 2000s and now is eyecandy, and in that regards Pathfinder doesn't present itself that much better than BG1&2. Combat wise the games aren't actually that different. I can't really think of anything Pathfinder had, that BG1&2 didn't (more complex ruleset of course, but I don't think that's what we are discussing).
