I'm going to have to agree with that. One of the things that we have all had to deal with is retconns and mistakes, at least when dealing with the 40k universe. In this case, multiple explanations have been offered that can deal with the timeline discrepancy. With that said? I can empathise with Adam France's frustration. In this case, though, I'm less after the minutiae and more after how things are going to be handled in general.
I've got my own interpretation of Marines and I'm just wondering how, or if, FFG are going to have me jaw dropping open with just how cool of a concept they've come up with.
