Yeah, that's the one.

Trailbreaker was part of the "Collectors Edition" series of reissues, which were all exclusives.

Others in that series included:
+ Ironhide & Ratchet (e-Hobby exclusive); since reissued in Encore
+ Sideswipe & Red Alert (convention exclusive); later reissued as e-Hobby exclusives. Sideswipe later reissued in TFC and Red Alert in Commemorative Series (CS).
+ Skywarp & Thundercracker (convention exclusive); to be reissued in Encore
+ Dirge (specialist toy store exclusive); since reissued in CS.
+ Ramjet & Thrust (convention exclusive); never been reissued since
+ Inferno & Grapple (convention exclusive); Inferno since reissued in TFC and Grapple in CS (sans chrome on hook )
+ Trailbreaker & Hoist (convention exclusive); Hoist since reissued in CS and Trailbreaker has never been reissued since.

The Collection Edition 2-sets all originally sold for 6000JPY each. Dirge sold for 3200JPY. But yeah... Trailbreaker, Ramjet and Thrust are the only Collection Edition reissues that have never since been reissued again.
