Even as probably no one is deploying XG-PON in new deployments (10/2.5G), I don't believe ISP start selling symmetrical services to residential customers as a standard, even if the PON itself is symmetrical. I know you can get from many providers a symmetrical service on G-PON, but that is an option, not the default.
Does anyone know the Asian market where they are using E-PON? After my very short search it seems they provide best effort up to 1G without any real plans...
