My vote would be to NOT make the corners into junctions. Having them be junctions does two things - it makes them not fit the N-Trak standard for track radius, and (from what I read in other discussions) it makes them not usable for our normal 4-track around layouts.
It sounds like others are taking care of buying things. I'll pitch in funds now or in January.
As for the wiring, should we re-use the wires on the existing corners?
