I wish I were smarter, or at least had more to go on. When Kobo moved to the ACCESS front end--a different everything requiring a different renderer--in support of the move toward an epub3 compliant format and reading experience, no old kepubs required any change on our end. I have no idea what eventually will hapen with Adobe. They may let the readmium folks do all of the heavy lifting on epub3 and one day it will all miraculously work with Adobe ADE.

OTOH, there may be a new scheme supported industry wide that leaves Adobe out of the picture without making people using ADE do anything at all.

Or not. It could be a holy mess. If so, it won't be a Kobo only mess.

If some sort of drm scheme is widely adopted that is widely supported across device manufacturers, vendors (including Overdrive) , and publishers, Kobo may have no use for kepubs as we know them. They could become whatever that new interoperable format ends up being--and it could be a seemless as the conversion to the ACCESS front end was for people like us.
