How is this argument debunked if the game is still large? 25-40 hours is a lot of time and that's if you play the game straight into the missions, most people will probably spend 45-60 hours i think.

25-45 is anywhere between a quarter and half of the original game length estimates.  How do you not consider that relevant?
