The international version which is the same as the enhanced yet to be released in Japan version is packed full of side-quest boss galore, including bosses from some of the Final Fantasy series.
Remember this game has been enhanced enough to apparently justify releasing it for a second time in Japan as 'Bravely Default: For the Sequel'.
There is a demo available in the estore and so far I am enjoying its promising vast scale, if you have it or download it be sure to press (Y) before you leave the first area to get a glimpse at what kind of budget this game must have had. (it zooms out so you can see its animated world in all its glory)
Release Dates
Australia: December 6th
Europe: December 6th
Japan: December 5th

I'm more excited for this game than Zelda, December 6th for me.
