Yes, Buzz was the very last FP machine and there is a Buzz CM standing at the entrance for FP returns who lets people know. I was going in to get Star Tours FP when she said loudly, "Buzz FP are the last machine." It was a surprise to me, as I hadn't researched here what the new disconnected FP are now.
Note that when we returned to use our FP, the first CM at the entrance let us in, but there wasn't a second CM collecting FP. So we just had to merge into the line, to the annoyed looks of the stand-by guests.
