I expect hat Canon will have a competitive edge over third-party lens manufacturers for some time.

IS integration: RF protocol allows that movements detected by the body can be used by the Lens IS (at least that is what I understand!). This ist quite different from the EF style  stabilization which relies on lens-based movement sensors only.

Mount diameter: third-party manufacturers tend to use the same lens formulas  for multiple mirrorless mounts, so they will have to calculate for the smallest mount diameter (FE), forfeiting any advantages of very large back elements (as seen, propable for a good reason, on most Canon RF lenses).
