The obvious concern is that as a privately held company they are not trying to impress the market for financing etc, the way in which Titan/TransEnterix is, so they do not need to present details and milestone achievements....so the question really is how good is it and when will it rolled out?
At this point, based on the vagueness of their website, it's safe to say it is difficult to ascertain.
Also, is any of their IP going to cause pending future litigation.
