DonDan has announced that the CF-SFX V2 is being prototyped, and is looking for user input into potential motherboard support. Dan Cases posted a short two question survey asking if users would prefer Micro-ATX or Mini-ITX motherboards, and if they prefer air or water cooling.
Based on the few initial responses in the Small Form Factor Network C4-SFX forum thread, mATX with Air Cooling seems to be the general consensus with ITX board prices and availability being a concern.

For those that have never interacted with DonDan before, he regularly listens carefully and considerately to SFF enthusiasts suggestions, with many being implemented into his designs. This hearkens back to the early days of SFF case design over a decade ago. If you visit [H]ardForum, the Dan A4-SFX original design thread from 2013 is still available to see and even post in. It’s comforting to see that even more than a decade later, DonDan is still passionate about his work.
