Noise "Reduction"?

I have not purchased newer Pentax DSLR body for quite a while for many reasons, but one of the biggest reasons is: current Pentax DSLRs are all not night scene friendly. As I do like night photography quite much, I find it is totally illogical to "upgrade" to get worse results.Actually, the K20D and K200D (and previously the K10D) are just some of the hottest and most noisy DSLRs ever made on
