I know it's gonna be quite a while before we even start hearing definite things about this game, but sometimes it's just good to talk about it, get your feelings out, vent the angst. :):
After pouring hundreds of hours into Diablo 1 & 2 over the last decade, here's some things I'd like to see from Diablo 3:
-Bigger inventory system. Going from Diablo 2 to WoW was great as far as inventory choices went, as the former had no pants, shoulders, trinkets, etc. The more customization in this area, the better.
-Lots of areas with depth that aren't tied to the main A to B progression of the game. We got a lot of attempted areas like this such as the Pit, the Moldy Tomb, etc. But these areas had little to offer, and have always been pretty worthless as a whole, with a few small exceptions (Such as some good item run spots in previos patches, before monster levels were adjusted). I'd like for there to be some hidden bosses, unique areas, etc. that can only be experienced by going off the beaten path. Not simple reiterations of other places like them that have no practical use.
-No AR (Attack Rating). This was a simple annoyance most of the time, and some classes were rendered utterly useless by this, especially in hell, unless they had utterly Godly gear (And sometimes even that didn't help). Titan Quest got along just fine without it, and I didn't even miss the *swish* *swish* *clang* *swish* sound that my frenzy barbarian use to make.
-If there's going to be Alpha Items (Such as Enigma) then each class needs to have a fair shot at them, rather than one or two items being sought by every class.
-I hope that classes can interact a little more cooperatively in this game than they did the last. In Diablo 2 it was pretty much solo play with cooperative if you wanted to, but the classes didn't really mesh well. There were some bonuses that helped out a bit but the most cooperation you see out of people is in Baal runs where everyone knows to point at the same spot and spam their skills at the right time. It would be nice if skills in different classes complemented one another.
-I would like to see gold have an actual use again. Since Uniques were made virtually impossible to gamble, gold has lost all value in Diablo II. You might occasionally see a "1 million 4 P Skull" game or something along those lines, but that's just sad compared to what it used to be. And unfortunately that only increased the problem of having "common currency" items such as Hr (Higher) Runes, or Soj's, etc. being the ONLY thing that people wanted to trade for. Again, Titan Quest had a great implementation for gold, as it could be used to unsocket items, respec your skills, etc. And these services became increasingly more expensive as the game went on, so the necessity for having gold increased if anything.
-Some augmentation to the socket system. Most of the runes and gems were utterly pointless in anything except "Runeword" combos. I don't believe I've put a gem in a socket (except for chipped diamonds in an Act I shield from time to time), in five years. It would be nice to see good Runeword stuff, but have it be more on par or worse with found Uniques and Rares (Which I would also like to see re-emerge as being more useful, and get rid of the abundance of useless mods that plague rares now).
