This is true. Freeview lags behind on hd for reasons of bandwidth, infrastructure and the recession.
Freeview HD - High Definition TV
Freeview - Home / Resolutions / About Products / Product types / Will high-definition television (HDTV) be available on Freeview?
The links are slightly encouraging, up to a point. In my case, I use capture cards to view freeview, so it will be a case of putting my hand in my pocket again, opening up the box & dropping in a DVB-T2 card as and when they become available.
