From what I've heard/read about Dexos, it is a GM-designed (if that's the right term) oil so that all engines can use it in their lineup. It is also a recognition that both synthetic and part-synthetic oils can meet the Dexos specification. And, as of about two years ago, Corvette is designed for Dexos-approved (or designated) oils----that means both full synthetic and blends of synthetic oil.
What it also means to me is that Chev engineers recognized that in order to meet the warranties they put on the Corvette, it did not require full synthetic. Whether that means Dexos blended synthetic oil is just good enough, or that full synthetic and Dexos-designated oils would be better, I don't know. That's for each owner to decide.

One other thing to note about the Dexos spec, if an oil is approved by GM, that manufacturer is also paying GM to use the approval mark. There are a lot of good oils out there that decided not to pay GM to be "Dexos" approved. Valvoline is one and here is their webpage addressing Dexos, http://www.valvoline.com/promos/dexos.jsp
Whether that will affect them from loss of sales or not is yet to be known.
