It's all down to what makes money. If the sales were there to keep models in production, they would stay in production. Note the PCR, PO1 and Compact pistol are all still listed in production, because they are very popular. The P-10 series has taken off like a rocket, hence the new models. There was exactly one CZ-97 chambered in 10mm, and the guy who shot it told me they practically had to saw the pistol in two to make it work. I believe that pistol is on display at CZ headquarters. As for 10mm, heck yes, I'd love to see a Scorpion in 10mm, best subgun cartridge out there in my uninformed opinion, but the sales aren't there to justify the tooling and dies.
40 S&W is still around, but not nearly as popular as it was back in the day. I agree the RAMI was a neat pistol and my son loves his, but it was a reworked shrunk down version of the CZ 40, itself a "use up" of leftover Colt Z-40 parts. As CCW guns go, it was just fine, but I guess the market didn't think so. The P-10S has taken that niche, and the P-10 Micro taking it one step further to compete with the Ruger LC/EC 9 series.
I make no excuses for what CZ does, but ultimately they are a profit driven company, and as sad as it is, (I miss the CZ 527 series!), they try to stay current and produce what the market here and overseas wants.
Now, having said all that drivel, if you want to keep certain models, it never ever hurts to contact CZ directly and let them know. If the company sees a market for something, well, we know how this works.
