Will there ever be another CFW for the PS3?

After official firmware 3.66 has been released, is there any possibility for another CFW (custom firmware) to ever be released? Or is there one in the making? Any info on CFW progress or possibility will be helpful. And please don't say "why don't you get a life and buy your games". I don't use the jailbreak to steal anything, I use it to use challenge lobbies on modern warfare 2 in private matches for fun with friends. By the way, my PSN is DW--Samuraii , add me.
