When everything is taken into account - IQ, range, price, availability in multiple mounts - it seems to me that the Sigma is justifiable over the Pentax 150-450 for the award.
I have no idea what the time parameters are. I think anyone considering a system that includes a long zoom can take a look at images made with the 150-450 and see that it is a very high quality lens.
Last year the K3 won some sort of EISA best DSLR award, so I doubt there's an anti-Pentax bias.
