Honestly, I think runes and magical tattoos are some of the most overplayed ideas in RPGs. But, admittedly, D&D v.3.5 hasn't had thorough treatments of either concept, yet.

I'd like to see a regular system for transformative or ascention magic. There are several base and prestige classes right now where you slowly transform yourself into some other or greater being. A class dedicated to that could be a lot of fun. Properly done it would be a toolkit of a class capable of going in lots of different directions.
Critter Magic, if it could be done in a non-pokemon way, could be cool. The sort of mage who muddles with the stuff of life and makes new critters. The kind of idiot responsible for the owlbear and kittenshark.
Those both sound extremely interesting. Mechanical nightmares, probably, but my favorite ideas always are.

And it would be neat to see shapeshifting done with spell-like abilities and / or supernatural abilities rather than spells.
Yeah, that's probably the "new magic" direction I'm most interested in. I'd particularly like to see a system based around temporary biological self-enhancements, rather than turning into specific forms.

I'd also like to see something more horrifically inclined- something dealing with reality manipulation and/or nightmares (tie in with the Far Realm?)
More Far Realm action would definitely be nice. I'd love to see a synergistic set of pseudonatural feats, rules for Wilbur Whatley-type unearthly hybrids, a base class version of the Alienist, etc.

What I really want to see, though, is some kind of magic-hacker. Basically, someone who manipulates the magic and spell-like abilities of others. New ways to utilize Metamagic feats (he could be the feat monkey equivalent of the fighter, but for magic-users).
I dig this idea a lot. It could include some new applications for Use Magic Device (which was always very much a magic-hacking skill) that include changing the way magic items
work, dispel / counterspell / spell redirection abilities, cooperative metamagic (like, spells that don't do anything by themselves, but which enhance the effects of other casters' spells), maybe magic trap finding and disarmament, maybe construct-specific manipulation and domination abilities, and so on.
Also, I could definitely deal with a whole damned alchemy sourcebook, full of new craftable alchemical items, and maybe some support for the more transmutation-related nature of historical alchemy, possibly even a base class. Maybe it could also include rules for the magical properties of various rare materials, not just for alchemical purposes, but for spell-enhancing material components and XP-replacing magic item ingredients. You don't have to contrive reasons for a non-intelligent monster to be guarding a pile of treasure when its very carcass
is a treasure.
