The release for Bayonetta 2 should be soon as the game has been rated over in Australia.
Bayonetta 2 received a MA15+ rating for “Strong Fantasy Violence”. The original Bayonetta received the same rating when it was released a few years ago.
This could mean Bayonetta 2 will be released very soon. The game is a Wii U exclusive. Nintendo should be announcing more details at E3 hopefully.
