I think our Rick was talking about doing the Sedburg for FSX ages ago... can't remember if it ever saw the light of day though
I think at Shoreham he said he was trying to sourcing some new pilots for it, but had the rest 'almost' done. FSX is so much better for gliding and now with a proper freeware winch launch, a new Sedburgh would be great. He also said he was very busy with work stuff too, so I think we should not expect it anytime soon.
