I'm not mad at Team Ninja, it was a farewell, and they were decent to do that, and i'm too attached to DOA as a series to let that get to me, but...
Why make that something special, why announce as something we should look foward to, why make a surprise?
They should have said something in their FB page like: "We will also give the game the last farewell or something".
It was in general just a bad move.
And honestly, the way it was phrased, makes me think that DOA 6 is not even on their current or next projects...
