CZC did make a 97BD conversion to 10mm but dropped it and (told to me) something along the lines of the gun couldn't handle a steady diet of full loads. The 10 has a new wave for now and I hope it is the new 45. My APC10 Pro is amazing. And have 3 Sig P220/10 and a G20 for hunting/bear backup. At full loads, its a great round.
CZ-USA made one total CZ-97 in 10mm. It worked, but the market apparently wasn't big enough for them to do it full time, especially counting the world market. Remember, there was no US plant at that time - maybe with using the Colt factory new models exclusively for the US market might be more possible. There is a video on YouTube of Zach shooting the only 10mm, which I THINK is on display at CZ-USA.
CZ has not eliminated the "bread and butter" CZ pistols, as the CZ-75 B, BD and Omega are still available, as well as the PCR, P-01, and steel frame Compact. The discontinuing of the 527/550 series was not a happy making time for me either, but we haven't seen what they plan on doing with the 600 series, especially with that hiccup with the switch barrel. I have to think they will expand the line once the kinks are worked out, and we might see a return of the micro centerfires. Also, the 600 series covers from 5.56mm/.223 up to 300 WinMag and 6.5 Creedmore and others. I hope it will be everything we liked about the 550 and the 527 melded together - I want a 600 Trail in 223 and a 600 Lux in 308.
