I was thinking it would be cool if we could have different formats for tournaments besides all swiss system.  Perhaps some round robins or other wacky variations (a la "Warzone" at chesscube).  I'm sure the chess.com team has thought about this, but I figured I'd post anyway and see if anything was in the works.  Thanks!

More diversity in live tournaments would be great, yes. Right now they seem a bit limited... But I'm sure the staff will be working on this in due time.

a round robin would be a good idea yes...of course the number of entrants would have to be ideal for it to be practical.
