Said to be similar in release to the recent Seeker 3-packs by Hasbro Asia (in Hong Kong), these two are apparently being released in South Korea... so I'm not sure if they will be available through the normal Asian sources of Hasbro Asia toys.

The two upcoming sets are...

Decepticon set - Galvatron, Octane, Astrotrain. (all are triplechangers, or intended to be)
Autobot set - Hound, Mirage, Ironhide.

No release date or costs known yet either.
