Alzrius said:3.5 is the game we want to keep playing, and see continued support for, so we don't need a 3.75 for Pathfinder.
3.5 is slow and cumbersome at higher levels (14+), it requires a lot of preparation for NPCs, ( I still have nightmares trying to create a BBEG monster with a couple of class levels, prestige classes , a template and some options from the UA) some classes and races are subpar (half-elves fighters anybody?). Altough I like the mechanics in 3.5 and were a great update from 2, I would like these rules polished and lightened. So I think paizo makes the right step moving to a 3.75
