It depends, the creator of bukkit has loads of work to do seeing the amount of new items added into the game. As far as I know he doesn't recieve ANY money from this unless some donations which imo aren't that much (I can be totally wrong I don't got the numbers) You'ld be patient and if you want this guy to hurry up you should go ahead and donate him some money for the great work he has been doing all these years. I wonder what happened if he stopped, considering the amount of derp bukkits coming out lately ...
