Seems this subject gets brought up about once a year and generally right around this time. Maybe it's in the hopes that this will finally be the year that we get a long awaited holiday surprise, and it piques my interest yet once again. It's been talked about endlessly, Brett has thrown out a few tidbits and details about the set here and there, but has never said it's not going to happen and instead has said to just be patient.
This is just pure speculation on my part, so don't anyone go reading too deeply into this, as Sergeant Schultz used to say "I know nothing!" The long delay and introduction of this new and improved Skinner could possibly need to coincide with a new release of the next version of Hauptwerk, possibly because of some new feature we haven't been privy to that this set would require that would be in the next version.
One thing I can say for sure, I've wanted a Skinner set for a very long time and I've waited a very long time, I'm not inclined to wait much longer, and come hell or high water I will be purchasing a Skinner this year before Christmas, currently the SP Skinner set is on my radar.
Again, as far as the rest of it goes, just pure speculation on my part.
