Yes, I'm sure that the Brizzle news studio was already HD capable a while before West Country appeared on Sky/Freesat ITV HD.
Sadly, those of us watching on Freeview or Virgin still get sodding Central HD. Even if only the "HTV" version was carried pan-regionally, that'd arguably be sort-of "better" (or at least "less wrong", so to speak) for e.g. Cornwall viewers.
I could charm the vultures off a corpse.
