Have you looked at the guest list for Nan Desu Kan recently? I believe NDK is going to supply us with a good mix of older and newer guests. From the former column: Lisa Ortiz. And from the later: Robbie Daymond. Don't know about the rest of you, but I'm excited for this convention.
We also have a bunch of friends who will be in Artist's Alley. You should go check them all out and exchange your monies for delicious comics.
