Correction. It only mentions July. I thought the "1" was on the first but turns out it's mentioning of "1 stage" so I misread it a bit.
Will likely release the tuesday after DOA festival with a trailer of it and the new dlc set at the event
It's Team Ninja, it's pretty much guaranteed to have glitches. But, if they release Aerial Gardens in DOA5LR, I will immediately forgive their transgressions.
