While Japan will be getting it hands on Star Fox 64's 3DS remake in a few short weeks come July 14, UK along with the US have to wait a few more months.
As reported by VG247 Star Fox 64 3DS is due September 9 over here, a few days ahead of the September 11 release in the US. It's not known at this time whether the game will again have a title change to "Lylat Wars", as the original N64 version did on its transition to these shores.
