In any case, I'm not keen on Tamrons and Tokinas because their rings tend to rotate the Nikon way round, which I find annoying when combined with a bag of Canon lenses!
If you look at the photo you can see the zoom ring rotates in the Canon convention. Maybe they'll have the different mounts rotate in different directions for consistency with the OEM lenses.
I stand corrected, it's just Tamron (should have looked twice at the photo in the post!).
I still can't see the point of this lens unless it has an ultrasonic motor. All the other major manufacturers have moved on (except for Zeiss and Leica, obviously) from this eighties arrangement. Who cares if it's built like a tank, I don't intend to use it to invade another country .
