You misunderstand. I mean that 12 will be coming with 8.2 and they need to work on it a lot before they ship it. Saying IE 11 needs a lot of work is pointless on the fact that IE 11 won't be the thing that ships with 8.2, 12 will. And they're probably already starting to work on 12 right now, since 11 is part of the RTM'd 8.1.
Oh I see, ya IE11 is still not good enough to drag me away from Chrome. Especially for development purposes.
