I wouldn't be a huge fan of a D&D edition dominated by anime style art. But I can tolerate a little bit here and there. In fact, I'd like a LOT of different styles of art from different artists popping up here and there in an effort to keep the game's art from being dominated by any single artist I didn't like.
For example, I really don't like Tomas Baxa's style of art. In fact, I kind of hate it. And while I can appreciate Clyde Caldwell's use of color and technique better, I don't like most of his scene compositions, stiff poses, and over-abundance of passive damsels needing to be rescued. But I can handle a little bit of them as long as they don't dominate the products. And I'm willing to accept product lines not totally dominated by art from Jeff Easley, Tony DiTerlizzi, and the late Keith Parkinson because I'm sure there are people out there who aren't as fond of their work as I am.
Variety, as far as I'm concerned, has been good, better than use of a single artist or style. If they didn't capture your imagination with Dave Trampier, maybe they got you with Erol Otus, or Bill Willingham, or David S. LaForce, or Jim Roslof, or Jim Holloway, ... do I really need to go on?
EDIT: On further reflection, if WotC convinces Rob Liefeld to do all of their art, I'm SO gone...
