Hmmm never knew about this, may hold off on the x1000 purchase to get whatever the 'latest thing' is when it is released.
It's probably a bad business move to hint about an x2000 this early on in the design process as their tiny market will now fracture into 'want one now' and 'wait for the actual fastest OS4 machine whenever it appears' however 
Let's put this into perspective: we are probably talking a year or so before Cyrus makes it to a mature consumer release. The AmigaOne X1000 is a stable, proven system and it's available now.
