Development progress phase isn't that much of a difference from the sounds of it. I mean the opposite of that would be the "development non-progress phase"? That sounds like they were in a testing phase prior to this.
They even said recently they only just completed like a running version of just the opening sequence of the game, likely what they've been doing is working on that small portion of the game with a smaller team. Now they are moving into actually bulking up the dev team for real development of the rest of the game ... which is going to take a while.
This game is not coming out anytime soon IMO.
