Perhaps, one of their projects is for Nintendo 3DS. Over on Facebook, a fan asked about a sequel to Contact, one of Grasshopper Manufacture’s Nintendo DS games. A representative replied, "No, no information on a sequel to Contact now. We’re not working on any games for Nintendo’s older portable systems. ;-)"
And later, the rep replied with another winking tease, "3DS? What’s that? ;p"
What’s that you’re trying to say? \(^_~)/
