If you're the only one using stock, you are differentiating yourself. You could also get updates out faster which would also set you apart. They're going as minimal as possible so to me it looks like they don't really want to continue the skin. I think some skins are good, like Touchwiz, and it's good that OEMs can add their own personal flavor but some, such as Sense, just suck IMO. I guess it doesn't really matter because Blur will continue like you said,but we just disagree as to the reasons why.
