Slowly but surely machines are becoming production models, rather than prototype, bulk machine orders are being signed, production facilities are being built. Yes it has been slow but there is a general feeling that production is starting to happen.
Yes it has taken a long time but there is definitely moves being made towards production, where Sigma should thrive, we didn't see 3, 3, 4 years ago. And behind the scenes you can bet a whole load more is occurring.
