Although, can you really blame them? I don't think it's unreasonable for most people to assume that the national broadcaster would be able to broadcast regional variations in HD by 2018!
I was surprised by your comment. It's all very well suggesting that the BBC should have a fully HD English Regional service, but of course there would be objections to the upfront cost of completing it all now.
The TV Licence payer can't expect to eat the cake, if they're only prepared to pay for the empty plate. The BBC have invested money in regional HD, but it will take time to roll out. I can't imagine anyone is really losing sleep over the delay.
ITV have made all their regions available in HD for revenue purposes, not for any noticeable benefit for the viewer.
There are plenty of pointers to viewers on BBC One HD to indicate when regional programmes are only available in SD.
