Well, they are working on Hexagon, at least. I've read that it's really going well. They've stabilized it and are adding new features, I think. I have it but I won't get the beta. I'll wait until the stable release is out. But I've read good things about it. I'm working on learning modeling in Silo. Working on it. Actually, working on getting back to working on it.
Yes I moved from Hexagon to Silo and I quite like it. Good to hear they are now working on it again as I would not rule out going back if the new version was good.
