Hi Max, I do hope that soon all the ISP's offer this tier. I do like the idea of an ONT that runs faster (2.5gbps) than the service it provides, removing a bottleneck.
Also EE state on their 1.6Gbps 'Busiest Home Bundle' a '1.3Gbps Speed Guarantee'.
How this would affect other users on the PON I am unsure of...?
