No they do not. They're simply based on the MPs listed on the
tfwiki page. So looking at just 2018, we had...
+ MP40 Targetmaster Hot Rodimus
+ MP41 Dinobot
+ MP42 Cordon
+ MP711 Convoy (7-Eleven)
+ MP34S Shadow Panther
+ MP10 Convoy (Golden Lagoon)
+ MP17+ Prowl
+ MP29+ Laserwave
+ MP36+ Megatron
+ MPM-5 Barricade (Hasbro)
+ MPM-5 Barricade (TakaraTOMY)
+ MPM-6 Ironhide (Hasbro)
+ MPM-6 Ironhide (TakaraTOMY)
+ MPM-7 Bumblebee (Hasbro)
+ MPM-7 Bumblebee (TakaraTOMY)
Granted that if we remove redecos and retools, as well as mould repeats, we have just four our of the eighteen releases being new non-repeats, or 22%.
But again, if we look at the early years of MP we see a lot of mould reuses too. In the first 8 years of MP we have only
6 new/original moulds, which are:
+ Convoy 1.0
+ Starscream
+ Megatron
+ Grimlock
+ Rodimus Convoy
+ Convoy 2.0
That's it. Out of the 27 MP releases in the first half, only five of them are new moulds - in other words, only 19% of MPs released between 2003/4 to 2011 were new moulds. So 2018's 22% new mould rate is
still doing better than the entire first eight years of MPs combined!
P.S.
This is what my MP collection looked like in mid-2011 (I hadn't acquired Rodimus Prime yet)

And here's what it looked like in mid-2019 (I hadn't acquired Black Widow or Hound yet)
