While I would like to see Cyinc again, they have toured several times recently. Also, Redemption is going on tour in Feb...
I think two great ideas would be:
Pain Of Salvation: make up for them canceling their progressive nation appearance (edit: thanks zedowns for correcting me). Would be exciting to see them play in the Bay Area as their first US appearance in a long time.
Arjen Lucassen: Might be able to get him to come out to the states since his new album is more along the lines of something he can tour with. Would be a great show.
Those are my two big ideas that I think would go over well.
