Autobase Aichi reports that Unite Warriors Devastator and Superion will be reissued in early 2019! Superion, due in January, is priced at 15,000 Yen (about $133 USD as of this writing,) with Devastator coming in February for 25,000 Yen ($223). This is a good opportunity in particular for those who want Devastator, whose aftermarket price has been climbing northward of $400 lately - even with shipping on a box that big, that'll likely be a savings.

Unite Warriors UW-04 Devastator has some upgrades in both deco and articulation compared to the Combiner Wars release in Generations, giving elbows to all of the Constructicons who originally went without. Superion's colors are more animation accurate (and thus, to be frank, kind of boring) compared to the US figure, but does include Deluxe Slingshot, who was otherwise only available in the US as an extremely limited "May Mayhem" release. Or as part of the G2 boxset!
