As mentioned, Gates of Firestorm Peak was designed explicitly for Player's Option series of books.
I think Combat & Tactics by itself brought back minis to the forefront of D&D. AS mentioned, in the pre PO world of 2e, the only type of representation of characters you might need is marching order and whether or not you were in the range of the fireball.
With C&T, introducing Combat Advnatage, Attacks of Opportunity and Flanking, yeah, minis were more necessary...
Personally, I"m of the side that believes it is a good thing that players are focused on the 4e combat table since I tended to dislike the focus on the pre-game build...
