Well the video and audio quality are better than the last episode and I think that one should be the worst of from the NHK Hall episodes. Which is nice as now that Kis-My-Ft. has been formed J.J.Express should be around the corner and I would like to have that in better quality.
Now that I remember that Junno had broken his leg his inclusion in this episode despite not being there makes a lot of sense. I am sure there were fans really worried about him and his place in KAT-TUN after an injury like that, so having him highlighted as being a member of the group, even though he was not there, was partly to relieve those fears. Especially as he probably will not be seen on stage for a while.
When first getting into fandom one of the early things I learned about NEWS was that they were paired with another group called KAT-TUN. This was also the way I discovered about the Johnny's agency and all the acts tied to it. But I think with this season of SC you can see the start of the lumping of NEWS with KAT-TUN that probably peaks around the time they co-headline the first SUMMARY concerts.
