I'm not sure if that was mentioned earlier, but the driver codes follow the release scheme of TTs ChoZ releases (obviously excluding Ultimate Reboot)
PR-01 ?
PR-02 Xtend (in this case Xtend+)
Yard skipped
PR-03 Jolt
Wedge skipped
Operate skipped
Eternal skipped
PR-04 Friction
Destroy skipped
Sword skipped
PR-05 Absorb
PR-06 ?
2 more drivers skipped
PR-07 Quest
PR-08 Dimension
(no new drivers in the ChoZ era, we could possibly count the limited edition Shining Ameterios 3 Destroy' in, that would be PR-09)
PR-09 Destroy'
PR-10 Ultimate Reboot (god series)
PR-11 ...
If that's intentional (it would be a major coincidence if not) it would mean the following:
PR-01: Volcanic or Volcanic' (as they did Xtend+ for PR-02 as well)
PR-06: Zephyr', Evolution or Zeta'
And it would also imply that we're unlikely to get Yard, Wedge, Operate, Eternal, Destroy and Sword, which is very unfortunate, however these tips are not that competitive or in the case of Eternal it would imply that Hasbro might still not like to do POM material which could lead to the question if Friction will have it...
