Sony and Microsoft certainly turned the motion-sensing heat up on Nintendo at E3 last week, but it doesn't seem like Shigeru Miyamoto is all that concerned at the moment -- he just told the BBC that while he's "flattered" his competitors are "moving in the same direction," he's "not worried at all" about Project Natal or the Playstation motion controller because "they don't have the type of depth that we're able to provide with Wii Motion Plus." Snap. We don't know about that -- we certainly haven't been blown away by Motion Plus -- but we can see why Nintendo's not sweating it just yet: the Wii's a runaway hit and a pop-culture phenomenon, while Natal and the PSMC are still tech demos without announced ship dates or even final names. That said, it's clear that Microsoft and Sony don't intend to just cede this space to Mario and Co., so we'll see how Nintendo fights back -- we'll tell you right now that the Wii Vitality Sensor ain't gonna cut it.
