Thank you so much for the replies and better link everyone.
I'll contact yesasia about the region code once a release is announced. Though it is encouraging that the blu-ray of the complete single collection works.
Edit:
The last group picture I'm so glad they did this for the fans.
One last time: another copy of the entire concert, in one piece, in full broadcast quality*, just in case you haven't watched or acquired it somewhere else already…
* i think. it's hard to tell with the automatic re-encoding that happens whenever you upload to any video site. but it certainly looks like 1080p30 to me.
