Why is LYD/YYS peaking now??????? The correct time is 'From All-England till War ends'...
Okay I guess you are referring to next year 2016 All England I guess. Well to be honest Lee Yong Dae / Yoo Yeon Seong still cannot convince me that they are the best MD yet. They are still the beatable pair. And this has also been proven. I still remembered how both of them have lost to unranked MD players before. Last year they lose tamely to Josche Jurwonne / Johannes Schotler. And they have lost to Mohammad Ahsan / Hendra Setiawan many times too. They have also lose to Mads / Mads before.
Anyway although they may have shown that they have won a streak of gold medals recently but it is still not convincing enough to say that they are peaking now. Perhaps both have shown signs of improvement recently but definitely they are not at the top yet. Hope it clarifies your question. They are not peaking now rather they are just showing signs of improvement.
