I don't think so, but it would be REALLY AWESOME if they reverted to rules allowing full groundwork, or opened up generalized submission grappling. Not only do I think it would attract more people, it would allow for a variety of up and comers to show their skills from Judo, catch wrestling, Brazilian Jiu Jitsu, Sambo, and more. I get the whole brutality of technical submissions, but they could still have the event with some limitations on that ability. I would watch Olympic Judo more often if that were case.
I also echo was pugpaws said about Tae Kwon Do. The problem with both styles in the Olympics is the watering down that has taken place, not that they are present.
