The next major release of Microsoft Dynamics AX will include a new Windows 8 style UI which is expected to be released in August 2014, so If you didn't start AX 2012 learning and implementation you will suffer from the HUGE gap in the Application/Technical area, specially Microsoft will release additional 3 releases (Not major releases) which are AX 2012 R2 in December 2012 and AX 2012 R3 expected in 2013 first half, and AX 2012 R4 in 2013 second half, in addition to that Microsoft might release some Feature back !!!!!!!!!!!
Sorry AX people, for the couple next year you won't have good sleeping :D
