While promoting the DS version of Activision's Goldeneye 007, the creative director of n-Space, Ted Newman, has made comments regarding the capabilities of the 3DS in an interview with Nintendojo. When talking about Winter, the horror game designed for the Wii, he expressed that the company is still interested in releasing it, but still has no publisher. But when about a 3DS port of the title he said “Yes, absolutely. The 3DS is really powerful”. He then explains that everything that worked on the Wii should work on the 3DS, and that the team could add more to the game thanks to the handheld's 3D capabilities.
Geist, a horror first-person game first released for the GameCube in 2005, would also possible on the 3DS thanks to the similarities between it and the GameCube. According to Newman, if Nintendo were to ask n-Space for a port to the system it can be made possible.
