GTS Centurion or 92x Centurion: Are these dropping in batches, being redone, or changed?

Looking for a GTS Centurion or 92X Centurion.

The 92x series looked like it was discontinued.

The GTS Centurion is not readily available/can't be found. I am having a hard time getting one.

Is the 92x Centurion discontinued?

Is the GTS Centurion being dropped in batches, being changed so none are available, or is discontinued?
