Maybe at some point they relize that SD cards are unreliable and they shouldn't be the boot drives, and replace it with IDK a HDD or SSD. Maybe they also realize that people use this as a desktop, so they make it compatible with regular cases. Also it would be nice if you can use an old regular power supply for it, instead of their hit and miss 5V 3A but actually 4A proprietary power supply. Maybe they realize that all the ports should be on one side, because having it on all 4 is bad for design, tolerances, everything. Maybe they also realize that cooling actually necessary with their board, because those Qualcom chipsets are becoming more and more power hungry. You know, something that is compatible.
I think at that point they can finally make an ITX motherboard, instead of reinventing all the bad ideas from 20-40 years ago, that were tried and discarded.
