Didn't someone finish an SSN style knux a while back. If you could find it, there would be much more frames to outline (oh joy ;-P)
Segmint, I really don't care how long it takes between updates, just whether he is still working on it or isn't. If he is, then I can wait a while, if he isn't I might try to pick one up and improve my animating (with his permission). (I can sprite, just not in all eight directions with good anims, I'm trying to get better though)
I sincerely hope he does finish them though. Also DashFox2007, photobucket is probably used for common unimportant updates, he might be saving some sprites for a good update to keep interest in this fueled. (like the life-icons)
EDIT: Missed the last two posts for some reason. I agree that looking on photobucket isn't the best way to see updates, but like I said, I don't consider 3-4 more sprites much of an update. Also there is school and Nitro does have a limited time on the pc, so I'd give him a break.
As much as it does look like he's making others do his work for him, I'm inclined to give him the benefit of the doubt.
