Office 2013 = Office 2011 for mac?

MS Office 2011 for Mac OS X is MS Office 2010 for Windows.

It should be anyway as it showed up around that time.
Even 2007 is better.

A new Office for Mac will probably be called 2014. But so far I don't think there is any beta or preview which is a bit odd. There is no official statement other than they are working on a new Mac version.
Maybe one that can actually match the Windows quality or come closer to it.
