Naruto is as strong as ever (I wonder how many times I've written this now?). Naruto is very popular among kids, yes, kids as in "we do not care about this being filler because all we want is action" (ah, I remember those days). I'd say the reason for no new merchandise or games is simply because there's no new material to work with... they will hardly create a Naruto filler game now will they. ;S (wouldn't surprise me so much I suppose but yeah)...
