It’s finally official. Microsoft is launching the new Office, aka Office 2013, on January 29. There have been lots of rumors that January 29 would be the day that the latest version of Office would be generally available via retail channels. But thanks to a tweet from the Office team, and a #Timeto365 campaign/hashtag — which I saw via Winbeta.org — we now know Microsoft is “launching” the new Office on Tuesday in Bryant Park in New York City. (Thanks for the heads up, guys! Luckily, I live within walking distance.) Microsoft released Office 2013 to manufacturing on October 11, 2012. The company made the final bits available to MSDN and TechNet subscribers, as well as volume-licensing customers, before the end of last year. Recently, Microsoft made $10 versions of the final Office 2013 bits available to volume licensees with Software Assurance as part of its Home Use Program.
