mm.. for now, no information about it, but I'd really love a blu-ray release! In fact, I asked for it (and I know many others did the same) in the online survey that was available after the concert.
I understand that since the livestream was available on the Zaiko system (owned by Lawson), a blu-ray announcement couldn't happen soon.
(as now, you can find some "not so official" video uploads of the livestream concert on Bilibili and download with tools like yt-dlp, but blu-ray quality, especially audio, is another level)
But I really, really hope for it! They could do some collaboration with Tokyo MX, and release the disc together with a limited edition of Magical Mirai 2026, or a Crypton/Sega collaboration for Miku 20th Anniversary, something like a blu-ray box collection with Lawson, Japan Tour concerts and DecoMiku! That would be incredible!
