I hear probably next year, Johnny. The original concept was actually penned as a naked streetfighter, and there was some discussion inside Triumph as to whether or not it should be faired or unfaired. In the end I guess they decided to have both (gotta sell bikes to the squids in this class, ya know). This is the last year of the Speed Four, so expect a 675-based naked next year. I don't know if it'll get the S3 bug-eyes, though.
This bike doesn't have much in common with the ZX-6R at all, except that it has two wheels, an engine and a fairing. Maybe more in common with the old Kawi triples? On closer inspection, you'll also notice that the styling is more distinctive than originally thought. I've seen a whole bunch of pictures recently that give a little different impression (trellis subframe, frame, swingarm--and the bodywork seems a bit more Euro than it does in the official pictures.) Everyone who's seen it up close has remarked how good it looks in the flesh.
In fact, I'm sure Sean and some MOtroops have seen it already at the press unveiling they did in Hollywood.
