Tamron 11-18 for Pentax ?!?

Hi guys,
does anybody know if there is any kind of explanation why Tamron doesn't do their SP AF11-18mm F/4.5-5.6 Di II LD Aspherical [IF] for K bayonet mount?!?
I checked it in my catalogue and on their official web page. And it really comes only for N, C and M/S mount.
Why???

Easy! Because pentax has the smc DA 10-17mm F 3,5-4,5 ED IF and the smc DA 12-24mm F 4,0 ED AL IF so the tamron lens just wouldn't sell :P

Unfortunately that is not the only lens Tamron does make in a K mount, including the highly regarded 17-50. In the last several years both sigma and Tamron have backed off making fast pro caliber lenses for Pentax. Why? My guess is market share........

I don't think so. DA 10-17 is fisheye and not corrected lens like tamron, and DA 12-24 costs nearly twice as much as tamron. At least here in UK.

If that's true, I just hope both of them will change their policy especially when K series DSLRs from Pentax had such a success. Anyway I don't understand it. They make Sony/Minolta mount, and not Pentax?!? I didn't think Minolta and now Sony are more popular then Pentax...
