Actually Mauser I disagree. I think they almost certainly would announce the results.
They need to show what European sponsors are getting for their money.
They need to block the competing announcements coming out of other research camps especially HP otherwise they will be missing orders or orders will be on hold.
They are championing the cause of EBM - they need to make sure EBM is seen as unique and competitive or best in class vs other 3D approaches
