Neither extreme makes sense: Leopard near final candidate? I don't think so, with developers still in the dark about (possible) important features, and the lack of the usual accelerating test seeding. And delayed in October for the sake of Vista support? That never made sense either.
The truth is somewhere in between. Late April seems JUST barely possible. End of spring is also possible.
An event could come sooner to DEMO the product and give a release date though--and it better come soon if it's going to reveal features that developers need to know about. (Maybe they don't. Maybe it's all Finder stuff or companion apps.)
I really HOPE the res-independent UI makes it. I find it odd that devs are not in heavy testing of that, since the cat has been out of the bag for some time. I really want that feature (Windows has it, in some fashion) and I hope it hasn't been back-burnered.
But I've never heard of any developer doing anything to get ready for res-independence. Does anyone have links suggesting this IS happening?
In Apples WWDC video from 2006 they told the developers to have their apps ready for resolution independence by 2008.
