The new version of the EN1090-2 is still a draft (albeit almost on the end of the project), so be aware that whatever I say can still change. But for the time being, no, there won't be a lot that changes for EXC1. Still no WPQR's required for EXC1, and no formal responsible welding coordinator, meaning no courses required. There must be someone however who leads the FPC system, but basically that can be everyone. And these are typically the most intrusive (read: costly) changes when implementing an FPC system.
