I disagree with you guys.
The game may need more time then anticipated, and whether it'll be released a month or a year from now, if it's good it's good and it will sell.
Furthermore, developers may choose not to keep us informed on their progress. Sure it's nice if they do so, but if they don't ... well, it's up to them don't you think?
Now WiF has an excellent update history, but as to Duke Nukem, well... and I'm waiting for that one too
In short, we'll see when it gets released, and only then we can judge the game I think.
In this case though, the developer is giving the press an estimated release date, which then becomes public information, but withholding it from prospective customers that are interested. I just don't understand the rationale behind that approach. It's not even a case of keeping Matrix customers informed, but he doesn't provide this public information on his own forums:
