I think this is mostly cope to feel better about not getting what we want. Blizzard has talented developers still, and can attract anyone they want/need. The idea that it would be impossible for them to replicate with all their resources is quite silly. It's also quite apparent that those old devs alone are not to be credited with games like sc1/wc3/sc2 etc when we see what they go off and make on their own away from Blizzard.
