If these come out from TakaraTomy they're likely to be the G1 characters again.
IDW is having the G1 guys (Bumblebee, Skywarp, Starscream, Soundwave, Shockwave, Jazz, Sideswipe, Prowl, Bluestreak) use their WFC/FOC bodies too. So yeah there is fiction on both ends that say these guys are G1 guys as well as fiction that says they're Prime guys. WFC still fits better with G1 in my book.
If IDW or Takara says he's G1, that's enough canon to make me put him with Classics.
I wish there were some canon to make Bludgeon work.
