Personally, I'm hoping to see some kind of system where you can take the skills useful for combat situations, and also take skills useful for social situations. I'd suggest simply increasing the number of Skill Points, but that'd just lead to people taking more combat related skills, and not taking any social skills, so I'd like to see something like this.
You have two sets of skills which you can choose from. The first is combat related skills, which includes things like Hide, Move Silently, Tumble, etc. You have a number of Skill Points which allow you to select a certain number of them.
The second set of skills are Non-Combat skills, and include skills like Knowledge, Diplomacy, Sense Motive, and Bluff. You've got a separate number of Skill Points to choose from that list. And thus every character will have some degree of Knowledge/Social/etc skills in addition to their combat skills.
I'd also like to see an option where every class can select two or three skills which normally aren't class skills as class skills. For instance, give the Fighter the option to pick Diplomacy and Tumble. Or give a Paladin the chance to pick Intimidate. That'd open up a ton of character concepts to players. After all, do you really need a "Knight" class when you can just play a Fighter? The only thing stopping you in that regard is that Fighters don't have Diplomacy and Knowledge (Nobility & Royalty) as Class Skills. But if they could add them as Class Skills, then they'd be set.
