Japanese toy blog has pictures of the Beast Saga Capsule (Gachagacha) toys. I'm looking where I can get a set of these (if you have a cheap lead, do share) but I would like to point out that this blog post shows how they're different. They're roughly the same size as the standard figures (maybe a hair smaller), but the arms seem to be unjointed. No weapons are included, but Liorga's head has a closed mouth and the bird seems to be unique (and exclusive) to this grouping.
More as I have it! And heck, hopefully we'll all have them soon.
