Just 15 to 20 years ago, chinese sports are no where close to the western worlds..just look at the medals tally at the Olympics. Suddenly, the government doubled or even tripled their effort in producing top athletes..and shazaam, their athletes are world beaters now. And we are not just talking about TT. TT has a special place in all chinese hearts, and they really take it seriously, and I don't think they will let it go that easily.
Like Dan said, they probably be up there for the next 50 years or so. Every time that we think we are a step closer to them, they take another two steps. The rest of the world may get one or two exceptional players, maybe even from WS Academy, but its no match to the sheer volume and quality players that the Chinese are producing. When it comes to team competitions and especially the women's tourney, the Chinese will more often then not comes out on top.
Please don't get me wrong, I do want TT, or any sports for that matter to be more open, and unpredictable, but until we start figuring out the best way (training and development) in producing top players (instead finding out what the Chinese are doing and copying), we still have a long way to go.
Another thing that have this wondrous affect with the Chinese is fame and fortune. In Brazil you have football, in the US probably is the big three.(American football, basketball & baseball), in Malaysia its badminton. Stop anyone on the streets anywhere in the world, there are greater chances that they will know who is Federer, Ronaldo or even Kobe, but try and ask if they know who Boll is, even Zhang Jike. You probably have blank stares looking straight back at you. Like I said before, until TT start offering bigger stash and rewards, we will never be able to entice youngsters (parents play an important role) seriously to venture into the game. Imagine this, the table tennis geniuses from the rest of the world are probably playing football or tennis or everything else, but table tennis. Their real TT talents will never be discovered let alone developed.
