It doesn't seem that there will be one. Apparently last year's show was indeed Yuna's retirement show (it was called that too) - not just from competitive skating, but from skating altogether. I guess they decided that there was no point in doing the show anymore if Yuna was not going to be in it, as the majority of the public obviously attended the shows mostly because of her, although they appreciated the foreign stars too. I personally don't quite agree with it - I think they could have kept the show going (perhaps involving other organizers, as I understand that the organizes were basically Yuna's mother and staff) so that the other Korean skaters had this yearly opportunity to appear before Korean public, if for nothing else. If the attendance went down a lot without Yuna in the shows, they could have made it more low-key and two or one show days instead of three (although the other side could be that the attendance would decrease even more without all the splendor of a high budget show and with a lesser number of star skaters). All that said, what I find a bit strange is that after the last year's shows there was apparently an announcement from the organizers stating that it was not the end of it, and that there were going to be even two shows a year like before the pre-Olympic and Olympic seasons. Granted, I didn't hear or read the announcement myself, someone just retold it on the FSUniverse forum, and it could have been false and/or a misinterpretation. Perhaps it was the case, as otherwise there should have been an announcement that they had reconsidered. I could believe it that Yuna perhaps thought she could continue to perform at least in this one show for her fans, but later understood that she had many other things to do in her life, and that leaving skating behind was actually the best option so that she could really concentrate on those other things. But in such a case she could have just said it to her fans in an interview or something, and I have read nothing of the sort from her Korean fans (or those who understand Korean) on the forums. I am not saying that she was obliged to do so, but it would have been considerate - especially if at some point there was an announcement about the shows continuing. But considering that there doesn't seem to have been either word from her, or an another announcement from organizers, it is very probable that in truth there was not an official announcement about shows continuing either.
So no more ATS 2015? Sad. Thanks for replying
