Incidentally, I haven't tried to look through the archived posts, but if Ledyard Sensei still has those videos he posted of the last Summer Camp, I'll be happy to point out (and explain) where what Saotome Sensei does is exactly what Ikeda Sensei is doing in some of his recent videos. Since Saotome Sensei learned from Ueshiba Sensei, I think the proper conclusions can be reached.
What Ikeda Sensei, and the rest of us, got from Ushiro Sensei was an organized set of explanations that made many of the elements Saotome Sensei had always had but did not explain, clear as discrete pieces that could be looked at and worked, distinct from other elements. Saotome Sensei largely just did stuff. Nothing was ever pointed out.
When Sensei and I were watching one of Ushiro Sensei's classes, he commented that he had been teaching the same things for well over 35 years. My comment back to him was "Yes, Sensei, but Ushiro explains it."
As someone who has taken ukemi from Ikeda Sensei for 35+ years, I can say that, while the outer form of his techniques is much the same, what he is doing is on another level and the experience of taking ukemi is quite different.
