True, we don't know for sure. But your claim in your post was that machines have been forgotten and are "just sitting in the warehouse collecting dust." You have not evidence of that either.
My point is that machines are not forgotten. You are correct that placements take a while. But with multiple distributors getting involved, I believe they will continue to place machines at an increasing rate.
Gary did admit that in the past some of their distributors did virtually nothing. Ace/Sanitis was one of only two that reliably were placing machines up until last year. I believe I saw somewhere that Ace/Sanitis decided to stop making public all of their placements due to requests from clients. Probably because pesky shareholders were pestering them. That does not mean they stopped activity.
So all that to say, I don't believe machine placements have stopped. At what rate they are placing currently I do not know. We should find out in Q1 report how things are doing there.
