Might have better luck with these answers if we start asking about 'modern' heads as opposed to 200x heads.
• Roboto 200X head
I'm afraid you won't see a 200X head for Roboto. It's the same design, just in a different 'style'. If you put the roboto character into the 'style generator' and turned the dial right to 200X - you'd get the hyper anime roboto look. If you turned the machine's dial to the left to 'classics' it would come out looking like the MOTUC Roboto. There will be no 200X heads.
I hope that answers your questions Macx!
