Square Enix held a live presentation for Bravely Default at Nico Nico Live earlier today. Here's a bit of what was revealed during the event, as compiled at Game Jouhou:

• You can skip the animations for summon spells
• New jobs include Valkyrie, Ninja and Summoner
• The game will offer a variety of methods for recovering your BP
• The hit count during attacks is determined by your job's level

The broadcast also had mention of yet another demo. The game's fifth demo will be its last one. You'll be able to carry over some elements into the final build.
