E10 Petrol by end 2021

That's great, but if they are re-branding unleaded to super unleaded, what about us guys on here using the current super EG; premium or v power etc?
If, the petro business is keeping premium brands, they would need additional pumps..i cant see that happening! Can you?
 
If I have understood things correctly the new E10 petrol is better for the environment but less powerful.

This is all guesswork but I doubt petrol stations would sell higher octane petrol unless they made money out of it - perhaps they will simply re-brand the higher octane fuels like V-Power and Momentum as high octane fuel rather than call it "super-unleaded" if E10 fuels go on sale?

This link suggests that if E5 petrol goes on sale incompatible cars would have to shift to using the "premium" high octane fuels on offer now.
