It would seem that the preorders on the soon to be released TetraJets have been a bust for the company, and they're closing after this run of production.
The team that brought your TRNS-01 (Arcee) , and the Quintessons are going out of business, just before they were to have released their legends sized minibot products too

See tformers for more info

Expect these to start going for crazy prices. Oh and if anyone would like to sell me their Arcee, please PM. Mine is getting a little fragile, and I can see it getting worn out with play and transformation.
