Right, you'd likely have to connect your old CAN-bus reader to the new system through an active PHY-to-PHY adapter dongle, sort of like a VGA-to-HDMI adapter, or (presumably, once it happens) a MIDI1.0 to MIDI2.0 adapter.
As long as the new version of the protocol is still formatted on the higher OSI layers in terms of reusing the core messages from the old version, and then adding new messages that are optional to the understanding of what's going on from a CAN1.0 perspective, then a change in the PHY layer still isn't really throwing the baby out with the bath-water.
