The mainframe is as healthy as ever due to its supreme stability and reliability. It isn't going anywhere anytime soon.
Computer Associates (CA) just has a nasty habit of acquiring decent companies, terminating their people, beating these new customers over the head for maintenance payments...and then CA doesn't enhance the software. It is their classic storyline repeated many times over.

Yeah, I heard that many times from the mainframe administrators. I was on the Digital minicomputer side and we managed to avoid the Polycenter/Unicenter stuff although it was certainly pitched to us.
