Nobody knows when the new HD EPG rollout will be completed because Sky are keeping tight lipped about the whole subject.
What is known is that the EPG has been rolled out to all Thomson and Pace STB's and then it was delayed for Samsung/Amstrad STB's "for on-going development" as it was found to be unstable on those .Then it was rolled out to 30000 Samsung's back in september,then nothing again till last tuesday when a handful of Samsungs got it(no official number's released yet).
Though the EPG guide has just re-appeared on Sky anytime, which is usually an indication of more boxes being upgraded so more Samsung's may get it either next tuesday or thursday.
As for Amstrad boxes they're due to be upgraded last,so it's likely to be next year before rollout's completed on them as we're nearly in november now and Sky wont continue with the roll-out during december/new year because it's one of their busiest periods.
