Seems pretty clear they are "hoping" for a Feb 2015 release.
Windows Phone exec Joe Belfiore explained what Microsoft has said before, “early 2015,” he says that the release should take place between January and February, “less likely March.”
Like I may have said way back: I REALLY hope WP succeeds. I have thought about trying that ecosystem, but the waiting I see most of you Icon owners going through combined with very little WP push and very low consumer visibility make me weary of its long-term viability at this point. I will say that the Icon, as it was sold, looked very solid spec-wise.
