Some users (including myself) report improvement when using Tungsten white balance instead of AWB. Some don't though.
That said, the K-5/k-7 secondary sensor function might be doing this 'automatically', without affecting camera WB of course. Just the AF module part.
Now if they fix this issue via a software/firmware solution, this renders the secondary sensor useless/obsolete.
Now if that happens, the K-5/K-7 loses marketing points for the secondary sensor, and buyers will be paying extra for a useless component.
Note that the word here is 'IF'. They might improve but not totally eliminate the prob by firmware (not intentionally but a technical limit), and that + the secondary sensor completely solves it.
Then we're all happy.
