Right, I meant they're unusual for Big Fruit. And also, the period between this reveal and release this summer is equally unusual...

I'd say that the lag between announce & release is a little more worrisome and something that I wouldn't want to see become a trend at Apple. I've always felt that a big part of their press was their general tendency to release right at announcement of a product or soon thereafter. Though, now that I think about it, I guess their OS releases have, by necessity, had to have some lead time associated with them.
