It is possible, but a lot of that will depend on what options are available down the road from the various chip makers. FW never gives specifics about long-term plans. In fact, they pretty much don’t release specifics until things are pretty much ready.
It is correct that the CPU and RAM are soldered. Unfortunately, this is a restriction from AMD and just technical limitations right now due to the 256 bit memory bus and the speeds AMD wants the RAM to run at. FW really liked this processor and saw potential for it, so they decided to build a computer around it, even though they would have to forego some of the upgrade-ability they normally strive for.
I think most folks feel Framework could stand to improve their firmware/BIOS update quantity and quality. Some have had more issues than others, and I think GhostLegion is one of the folks who are fully disillusioned at this point. Understandably so. I’m one of the lucky ones who has had no real issues, but I still would love to see Framework improve in this area. That said, technically they continue to provide software/firmware support well past the warranty period. But they’ve also dropped the ball in some cases. I think they are trying and have good intentions. But I think there is not only room, but a need for improvement.
