without seeing a changelog line saying "Molten Front has now been fully scripted and opened" I don't think so... it's a large open instance with a lot of phasing and quest mechanics so I'm not expecting it until next march... assuming they keep working on Hyjal until it is "100% done" and not shifting their attention to a zone that doesn't work at all (of course everyone knows which one I'm talking about... the reason 84-85 was such a pain in the a** before we got deepholm)
Yes, I agree with you, Islingr.

I'm afraid we won't be seeing Molten Front for quite a while. But I do hope we will get to see it, some day.
