^ Normally AKB concerts take 6 months+ to get released. Basically, I think this is a rush release to get it out before the re-scheduled 2nd concert, so for now is DVD only. You can see from a couple posts above they are doing special editions to be sold only at that concert, and it's official online shop exclusive for a few weeks before general release.... I think a Bluray will come out later, about the normal time they release concerts, and probably packaged with the 2nd concert... there's also all the sister group SSA concerts to release...
