So far...
Me (V. Akiha, Sacchin), Chun (H&K, Satsuki, Kohaku), Tsubasa (Akiha, V. Sion, Hisui), Alt (Warakia, Kouma), Shobes (Nero), ZeroXOZ (Warakia), my brother (Len, Kohaku, H&K), Yau/Dakanya (Akiha), Mizuki(NOT COMING >_>), LastElixir (Akiha, Nanaya) and probably more I am not aware of. If you are coming and aren't on the list, post here.
With Zero, my brother, and I, we have three laptops with 17" screens which should be just fine for MBAC unless someone actually cares about the LCD display lag >_> The one thing we will probably lack in are adapters, sticks, and pads. Please bring your own and extras just in case.
