The problem with power 9, and likely 10, is that it was far too expensive and hard to get. Even two years after it was announced you had to talk to IBM salespeople, and the server was about 50% more expensive than an equivalent Intel. For a while they had pcie4 before anyone, and a strong backing from Nvidia. Those are both gone.
