Not surprising though, it hasn't had a refit since 2009. It's also still using Aston rather than VizRT.
I wouldn't be surprised if Astons were replaced by something other than VizRT in the English regions that are still SD.
Salford, Plymouth, London and Cambridge got VizRT as part of a wider upgrade/relocation. The SD Astons that other English regions still have (Greens, Reds - possibly even Motifs or Mottos?) will be upgraded before full refurbs I expect. I wouldn't be surprised to see a much cheaper option being deployed as an SD interim.
Someone told me recently BBC Cardiff are still using an Aston Red for Crimewatch's end credits !
That could well have been the case when it was an SD show from a studio in Cardiff (and may still be the case for the SD Crimewatch Roadshow daytime series) However I think now the show has relaunched as an HD OB (and changed formats) - I suspect something else is used.
That era of Aston was a perfectly good SD CG, and if they'd simply made an HD version of it with slightly improved animation they'd probably still have a business... Pixel Power's Clarity has picked up a lot of HD jobs that Astons did in SD, along with Chyron and Viz. (*)
(*) Aston did make an HD version of the Aston Caption (think it was single channel, unlike the 4) for the Eureka 1250/50 standard (just as Quantel made a 1250/50 Paintbox)
