^Yeah I edited my post when I shouldn't have. I originally had it saying 4+ years to develop A PERFECT one 
Usually launch engines have a 2-3 year development, then they are modified throughout the generation (especially the case with multiplats). I'm guessing bigger engines used on exclusive games that come out a year or two after launch probably have that longer development time. I'm just guessing on this whole thing, it just seems like from the description it would have been wasteful to throw out EVERYTHING from the Halo 3 engine since I'm sure some aspects will tie over and receive further advancement.
