Freeview HD has now gone live from the Crystal Palace and Winter Hill transmitters. Described as a "technical launch", it's not aimed at consumers, which is quite handy as you can't actually buy a DVB-T2 receiver anywhere yet...

Obviously once this fully launches, we'll start to see massive uptake of HD, and all of those people with HD ready TVs that have never pushed anything HD through it will be able to get a free HD signal.
