I came across this. I am not familiar with any of this, so I had to do a bit more research. This comes from deputy editor-in-chief at Shogakukan. Sho Kobayashi confirmed the news easily enough after sharing their congratulations for Blue Orchestra overall. This is a surprise to be sure, but a welcomed one!     Translation:  What!! "Blue Orchestra" has been animated!! You can actually listen to the performance scenes of the violin and orchestra along with you
