I think Grench nailed it.
I suspect that the community is split about evenly between those that want new sensors, those that don't and those that don't because they fear it will cause even more delays. Also, some people are already overreaching in purchasing the Pyra. Some additional cost might not sit right with them, especially since the (pre-)order has essentially been placed already.
There is nothing wrong with looking at better sensor packages. I certainly wouldn't mind the additional sensors, but I would not really miss them either. In my opinion, at this stage getting something out of the door is most important.
