VLC 2.0 is a major update especially on the Mac OS X platform. It would get a major visual overhaul in addition to support for Blu-ray media and native full screen support.
Windows edition would not be much different visually but there are going to be tons of other updates and enhancements.
They are going to make available a 64bit edition of VLC for the Windows users this time around.
Linux and Android users would also get a similar update.
