This is already impressive.
My only concern with announcing it early is that you will get many many people asking you when it will be done. Perhaps you will get this asked once a week at least.
I am really interested to see it with AI in there, because in the end the AI/gameplay is very important for this game.
The graphics are amazing yes, and the movement and smoothness of the game are great, but now it needs really good AI.
I really hope there is both a 2 player and 1 player game in there.
I think it will be hard to implement the AI and the 1 player game - I say hard, but I am sure you are up to the job of doing it!
EDIT: For a game like this I would have worked on the AI first with my own programmer graphics, then worked on the "nice" stuff.
I sound negative, yes, but I know how hard it is to keep the working going on a project and how hard it is to make a game play right.
EDIT2: On Blue Angel for example, I had to re-code the AI more than once - 1 to make it fast enough, 2 to make it fun enough to play and it is more simple in it's AI.
EDIT3: I have gone back to one of my unfinished games recently, and I am working on finishing the menus and presentation, but also I am working out how to make it more fun to play.
