I think that Naraku just might get all the shards of the shikon Jewel . by the rate Inuyaha and the outhers are going I doubt they will be able to gather all the shards of the jewel before naraku. Not unless they can sucessfully kill naraku and get the rest of the shards from him. They also need to find a way to get the shards for koga as well. And find a way to keep kohaku alvie when they get the shrd out of his back.
