Well, 120-172 hp, the sprung Carraro front axle, ... that speaks for me in favor of a major facelift for the Forterra series.
The Forterra (apart from the CL) already has 120 to 147 hp. Maybe a new gearbox + rear axle which allows + 25 hp? 
The engine cowling looks 1:1 like that of the current Forterra HSX.
In my opinion, a common platform for only part of the Forterra and the two almost identical Crystal models would make even less sense than the Crystal as a separate series already does. 
The Cystal "series" already makes little sense as a "series" today, because with the well-known gearbox/rear axle it hardly allows more than 170 hp.
Why do you still need the Crystal if the Forterra had more power (only +17% more) and there was a new "Super" series above the Crystal? Excuse me, Renze, but I just wouldn't see any sense in that - neither in marketing nor in the market. 
Yes - we agree on that. Zetor needs the 200 hp class to keep its customers and dealers. We've been waiting for this step since Maxterra.
But I'm afraid Zetor, just like with the smallest models, just hesitated for far too long and watched the market being divided among other brands (Kubota, Branson, Iseki, etc.).
Unfortunately, the clocks at Zetor run a little slower...
100% agree
That's why I think the new models will be Forterra. That would make the most sense to me.
Yes, well, there have been rumors (at trade fairs) - just nothing concrete. What is currently being introduced looks really good at first glance. Let's hope we won't be disappointed. 
On Agroportal24h.cz there was news in 05-2022 about new models that were only referred to as "M2023+" and were supposed to go into testing at the end of 2023. Maybe this is now "M2023+"?
