As if this is a daily need... that's a minority of wedding photogs with low sensitive AF modules in their DSLRs. The reasons for DSLRs get more desperate from day to day 
I mean, nothing against existing DSLRs - I have more of them than ML. Wait. No, counting all cameras without a mirror, DSLR are a minority here. And imagine, my roughly 12-15 year old Sony DSC828 works as well with IR LEDs as with laser patterns in low light situations, and I bet it's only CDAF...
Anyway, there are gazillions of DSLRs around these days, new or 2nd hand. What could a new model have to offer the older don't have? All I'm saying is, it's pointless to work on new bodies. See, Pentax already understoodÂ
