nvidia probably will not going to rush out their new sub 75w part.
I personally don't care that much about sub-75W and would be far more interested in sub-$150. It is merely coincidence or convenience that most modern sub-$150 GPUs are also sub-75W.
We'll see if and when the rumored GT1040 materializes. I wouldn't be surprised if it landed with a $150 launch MSRP, just like the 750Ti.
