One thing I would REALLY like to see (but I think some others' comments about it messing with some people's sacred cows are accurate) is a completely CLASSLESS system -
everything for classes done with skills and feats. The ultimate in custom configurable characters. And that big area of the PHB previously absorbed with classes? Well, obviously part of it would be taken up with the extra feats and skills necessary, but I'd like to see a large section put in on acting, ROLEplaying, and a bit of discourse on the importance of the tone of the campaign - how some campaigns emphasize the STORY the characters and the DM are trying to make together, while others are more about the racking-up-the-score, metagaming, munchkining and kicking butt aspects of the game. And both are okay, but that it is important to know what kind you are getting into and play accordingly.
Also, I'd like to see Hasbro\WOTC start leveraging some of their other properties for sourcebooks - just to give us more material to snitch stuff for our own campaigns from, if nothing else. And I don't just mean the obvious stuff like Dark Sun, Spelljammer, and Alternity. I'm talking about Transformers, Zork (if they still own that, and if not, they should reacquire it - it would make an awesome campaign setting - and it sure as heck hasn't made any good PC games in the last 5 years), Pokemon, Magic: The Gathering, and so forth. Of course,
this wish doesn't
require a 4th edition, but I thought I'd mention it anyway.
