Tamron puts internal motor on 18-250 lens

I see that Tamron is making up for the mistake of not putting an internal motor

on the Tamron 18-250 lens. Before, you could only manually focus this lens on the Nikon D40 and the D40x. This obviously should be good news for people who own the D40 and D40x camera.But I think they should have gone a step further and made a image stabilization lens also. Yes, I know they have a new lens( 28-300 ) image stabilization lens coming out soon but the new lens gives you a 42-420 which is great on the tele end but you lose the wide angle.
