Man, imagine being an ammunition manufacturer right now. You had a somewhat-less-than-successful go with introducing the .327 round, then you had what appears to be an outright dud with the .30 super carry. Then some guys talk S&W into making something in the 40-year-old .32 magnum and people go nuts for it.
I guess they're probably just happy that like GJM said they can pivot between making those calibers easily enough...
(I do wonder what the actual sales numbers for those 3 calibers look like a year ago compared to today.)
