As with most Vapourware the longer this goes on the less faith I have. Even if it does get released it will probably be pants. Just like with Duke Nukem you can't produce a game over that long a period without some of your code and ideas looking very outdated compared to others.
And even if by some miracle you release your long term project, the long wait has blown fan's speculation out of all proportion to how good its possible to be and it suffers by comparison to an ideal.
You must fear your target, yet respect it, like the crocodile respects the helicopter.
