There will be a new Nintendo Direct tonight at 11pm Japan Time which will cover software coming this summer for the Wii U and 3DS. Not sure why they need to throw the 3DS in there considering they had their own Nintendo Direct not long ago. Either way, all territories will have a Direct. Links are below.
