XSEED previously announced a Fall 2013 launch window for Senran Kagura Burst in North America. The company is still pinning down a final date, but it sounds like the game will be out sometime next month.
On Facebook, XSEED says Burst is planned to hit the eShop in “November-ish”. The title is also confirmed to be less than 2GB.
“November-ish on the release, very big on the size of the game (but less than 2GB).”
