The short answer is nothing. Now that's not to say I wouldn't play it under any circumstances. I can certainly conceive of the possibility of D&D 5e being a more enjoyable gaming experience than Pathfinder and, if that were the case, I might be inclined to switch. However, I know what the parameters are for the redesign of D&D and they don't excite me. WotC has tried to slaughter a few sacred cows since taking over TSR, but despite the protests of the more vocal critics to the contrary, in my opinion, they've mostly been cosmetic changes. Feats and skills add some complexity, but the fundamentals are intact, hit points, armour class, class-and-level character design and advancement. It's all still there, it's all uniquely D&D and it's all untouchable. Whether the next iteration of D&D looks more like BECMI or D&D 3.x or AD&D is largely irrelevent to me because all those versions of the same game still exist and they all share the same flaws in my mind. Here's the thing though. I don't think D&D 5e should change a thing. Ok, they should change a few things, but they are mostly superficial. D&D is what it is, warts and all, and if they can "Unite the Clans", that's great. But with what I consider to be far superior games like Legend, BRP and Traveller out there, it's hard to get too excited about ascending vs. descending AC or whether dwarves can be wizards.
