Yes and no.

Currently sites like torrentz.com give multiple trackers for torrents so that you can get the best set of peers/seeds for a torrent. These sites are going to become moot.

Also the legal issues associated with running TPB is going to literally go away for all future business. TPB can't be held responsible for holding an MD5 hash of a file, since they don't host trackers anymore they won't be responsible for even facilitating anything. Basically the record industries have to go after the customers yet again.

The only thing left is an IP masker mechanism which is super easy to use in torrents and torrents will become completely untraceable :P ok fine someone will find a way.
