That would be cool but the article does have a point by saying it is similar to Judo. I would have to agree with that statement but I am not a BJJ player or Judoka so maybe they would disagree.
The ADCC has proven that BJJ is viable, the sport is growing like crazy, there would be interest in it... but the IOC are uptight sons of bitches so we'll have to wait and see. No chance MMA gets in.
Gotta be honest though, if BJJ is in the olympics, a Shinya Aoki vs BJ Penn BJJ match would be awesome.
