I won't even guess as to the actual % of completeness. I do want to say for the benefit of those who have seen the games in progress, but have not actually built a game before, that you can have a game that LOOKS complete and still have TONS of work to do. Code to write and test and debug and test and rewrite and test and debug again. Animations to produce and optimize for all scenes, all scenarios. Service menus? All of this is assuming that all the toys function as intended and that the playfields actually shoot well.
I won't comment here as to what I think the actual state of things is because John's tone is becoming increasingly threatening. But anyone who has spent any time working on a pinball machine knows that you can have a pretty box full of pretty things and still have a long way to go until that game is ready to ship.
