Although we already had confirmation that an HD version of Mighty Switch Force! 2 was coming to the Wii U, it's nice to have an estimated release date of October, which was confirmed recently by WayForward's Matt Bozon.
If it's anything like the Wii U update of the original game it'll feature completely new graphics, brand new hyper stages, and remote play support. If you haven't gotten around to Switch Force! 2 yet, the Wii U version will be the perfect opportunity to do so.
