It seems as though it is becoming more common for new digital cameras to come without low-pass filters. I learned quite a bit from reading the excellent answer here: What is the difference between the newly launched Nikon D800 and D800E? I took away from that this key point:
With the sensor resolution now sitting at over 36MP, though, there are a lot fewer instances where the detail you are trying to record cannot be resolved and reconstructed accurately -- especially if you are working in a studio
The D800 obviously has massive amounts of resolution, but other cameras such as the Nikon Coolpix A with 16MP or the Pentax K-5 IIs with the same 16MP sensor - are not really in the same 30MP range. So why now are digital cameras switching to remove this filter?
This might be a duplicate of Why is a physical anti-aliasing filter still needed on modern DSLRs? but I guess I am asking the opposite.
