Serenity hits the sequel jackpot?

Cinematical say that they have heard a rumour (it's getting tenuous) that $30 million was the amount of dosh that Serenity had to make to guarantee a sequel. And now it's made that much. So will we see a sequel? My guess is no. Studio execs will be happier to regurgitate old films made to look new and shiny in their constant quest for more $$$$. Capitalism sucks.
