Nope, that's the latest update on his practising it since after ACI when he said he planned to begin training it again after JNats, iirc.
The 2015 footage is all we've ever been shown, though I bet they got some at media day last year. I think the first we'll see of it is when he lands it in competition practice and after that they'll air anything they've collected in a documentary.
I'm 100% sure that program will be an experience on par with Mezamashi.
