They never said calendar year 2012 as far as I'm aware. They said "coming this year" in June. This could be interpreted as anytime before June 2013. I wouldn't get your hopes up for Makeb before the end of 2012 because I don't see it happening. I think it will be more like mid February if they keep on their 6 week content cycle.
Indeed. Or it could mean "coming this fiscal year" if they were talking to investors. Either way it will be spun to their advantage. I agree it won't be until sometime in 2013.
