Yeah, a one year delay is a pretty big oops, but it’s not really a solution to the problem anyway. Except that 450b gets rid of the hated speed caps and also enables 5.1 GHz sub band. I’m not thrilled about SMA connectors on the top, KPP included a nice mounting post for the current style connectorized SM, I’ll have to see if it still works with the new SM.
What they probably need is a slightly larger and also deeper parabolic dish, get the gain back to 25 dBi, and better sidelobe performance. Or get to the bottom of why the 450d/450b style dish seems so much more susceptible to reflection and multipath degradation. I think Cambium expected higher xmt power would compensate for lower antenna gain, but that does nothing for downstream. I heard a rumor they were redesigning or eliminating the cable gland? Was that mentioned at Wispapalooza?

It looks like the old style SM was discontinued. The Old SM + Reflector was said to have 25dbi of gain. The replacement 450b "high gain" integrated dish is 22dbi. Are you kidding me?
