That's not to say that it's not coming out, just that there's no announcement, and that we should therefore not expect its imminent release - which was something we wondered about with the advent of the recent patch. Pete Hines, who tweeted the news of the non-announcement, followed up by saying "I was simply stating that expecting/demanding something today is unfounded. Not that news is never coming." SO MAYBE IT WILL BE ANNOUNCED. IT'S ANYONE'S GUESS.
Oh well, anyway, that's a shame. We'd just imagined it had been announced. I'm going to pass the time waiting for announcement by installing one bajillion mods from Skyrim's Steam Workshop and seeing what happens. Crabs wearing monocles, probably.
