After Naruto Shippuden, I think they should have a new show called Naruto Nara.  It would be a prequel to Naruto Shippuden.  It would tell the story of Naruto Nara.  It would tell of his upbringing, of what he endured, of his struggles and defeats, and how he became so tough. 

It would also tell the story of what Lady Tsunade, and her daughter have been doing all this time.  We know what Orchimaru has been doing, and we know what Jiraya have been doing.  But we don't know what Lady Tsunade has been up too.  It has to be more than gambling.

Then also the Naruto card game would continue.  They would be able to have more sets for it.  Also that's more Manga and episodes they could make money off of.  After all it's "merchandising, merchandising, merchandising."
