I'm a dealer. First, Classe is part of the B&W group which was just acquired by a Silicon Valley firm which will understandably make some changes but to this point, nothing formal has been announced. From what we've been told, Sigma will remain as others have said but the new Delta series has been put on hold. Whether production will resume and move offshore or otherwise has not been announced. At this point, reading any further into anything is a waste of bandwidth. I'd guess BW Group hasn't made any final decisions.
It's also sad that people have such a misunderstanding of offshore manufacturing. I'd guess most have no concept of the dynamics and have never been anywhere near a manufacturing facility in China or otherwise. But hey, the internet says everything made in China has been built by untrained, underpaid children who work 25 hours a day with no food, water or sleep and if it's on the internet it must be true...
