I don't really care what they do with bonuses, the issue with 5 isn't the way research is conducting (although tying it to population has it's problems. I liked commerce better). The main issue is the tech tree being completely inflexible. In civ4 you could beeline stuff, trade it around, backfill and slingshot. Every strategy had tradeoffs. Civ5 it's like you can't go more than 1 or 2 levels deep without getting everything prior cus everything's a prereq and the tree just isn't that big either.
From the designer comments so far, I really get the sense that they think Civ V was way too strategically inflexible, and that they want to change that. Which is a very promising attitude for Civ VI.
