With Leopard I think the new features are largely developer candy.
That's impossible to say, since some amazing parts are said to be kept supah-sikrit(tm)... However, unless you're in the Early Start Kit program, believe me, you haven't seen half of the cool developer-centerd stuff in Leopard. Apart from that, there is no such thing as "only good for developers", any improvement for developers inevitably is an improvement for end-users.
