The person who drew the ascii progress-bars was joking, but seriously, why not?
Pros :
People can see that progress is happening, without knowing exactly what it is (and thus no spoiler)
Rough estimation of how complete it is, with no release date (and hence no deadline)
should not be too dificult to impliment - simply a row of images, some with that section filled in, some not
(I should point out that I cannot be sure on this point, I only know very limmited HTML, and no PHP)
Cons :
gives very little information about what is happening, less than the somewhat spasmodic news postings. However, the news-postings are still good, I see no need to do away with them.
It will need to be maintained. Someone will have to decide how complete it is on a semi-regular basis (2x weekly?)
it will probably not be accurate. But that\'s not very surprising, considering the accuracy of progress-bars in general, combined with the un-certian nature of programming (EG: commercial game release schedules) - it cannot be helped if a major bug is found at 99% which holds up the release.
