Killzone 2 came out nearly 4 years (3 years and 9 months) after the cgi demo was shown. Then adding the time to actually make that cgi movie and to come up with the ideas for it, the whole pre-production time.
So from the first drawing on paper to the final release, i still say 5 years of production time
Improvements are caused by people who complain
