Maybe they're big on chaos theory?
It does feel a bit like they keep re-inventing the wheel with their construction systems. 
Steck worked, and looked good in the process. 
System-X works, though it does leave ugly pits and holes, and is a nightmare fitting all those stupid connectors (and I find they tend to drop out or disconnect from the wrong end when moving or breaking down setups). 
Now they appear to be abandoning system-x for various clips or lack of clips, where nothing can connect to anything else, and sometimes not even to itself, if the walls keep falling off.  
I think Hans Beck is quoted in 
Story of a Smile saying "everything fits". Now everything is separate and falls apart.
