That's likely (although not immediate). This year's Itanium 9700 is the last of the Itanium line and according to the roadmap here:

They plan to containerize HP/UX and run on x64 Linux, that sounds to me like it's just a plan for a run out to EOL.

It's a real shame that the last line of System V Unixes/ Unices / Unii is starting to die off. Market share aside, it's sad that the history of UNIX(r) appears to be coming to a close...

A very undignified end to a wonderful OS (BSDs aside!)

The BSDs are not an aside. You'll also find macOS hanging out in the FreeBSD family tree.

The days of paying vendors massive sums of money for an operating system are over.

To clarify - I agree the BSDs are keeping Unix alive, however separating BSD from those Unixes with System V roots which are starting to wither and die is the point I was making - hence the (BSDs aside) addendum.
