Interesting post Panta.
Did you notice that every single art you mentioned, not one was actually a "TMA"? Bjj, TKD, Kyokushin Karate, Judo, etc- these are all gendai budo or variations there of.
MMA has as pointed out by Willy simply put a spotlight on the way training is carried out. With all these chances for people to go out and test themselves in the relatively safe environment that is the cage/ring, the fight has been put back into gendai budo "crowd".
I love a certain type of unnamed japanese styled jiujitsu, they have in the last 15 years gone from a kata based drilling school to one that spars intensly and on a regular basis. These guys are slowly turning out martial artists that can really fight (LOL, imagine that!
) but are still keeping around the budo aspect that appeals to so many.
The techniques have not changed, the way they are trained certainly has.
But I agree with you Panta on the level that these "perceived traditional arts" are making a comeback as far as mma goes, but as far as the business world goes- they never left and are now and have been stronger than ever.
