Raindrop R2 is currently in production. It is a CtrlAlt GB. And it uses Cherry replica legends.
Anyone wishing upon a star for a full set of double shot PBT caps can just keep right on dreaming. We have already been told by SP that the shrinkage rate problem makes it near impossible to do a full set of DS from PBT. And if they were somehow able to do it, it would be so cost prohibitive that no one could buy them.
Best bet for classic Cherry beige is to wait for someone to run a GB for them through GMK. The reason to keep doing sets from SP is that they can do colors and legends that GMK just can't/won't. But if it's a true replica set, of existing colors that GMK has, there's no reason not to go the GMK route.
I believe Bunnylake has said that Toxic will be the last CtrlAlt GB with SP for a while. I think he has plans to do some cool stuff with GMK. And perhaps some classic replicas are in those plans. We shall see.
