Another addition to the list in the first post (they just keep on coming)...

According to Kapow Toys, the two Japanese Dino Cassettes that were released in the Studio Series with golden Bumblebee toys, will be released as a 2-pack like Diaru and Noizu.... and will come with a single-packed Rumble toy (the RED one).

They also note (which I couldn't tell from the official images of the single-packed Frenzy toy - which could just be a mock-up with a regular Frenzy toy in the pack) that the reason for the single-packed Rumble and Frenzy (since they are also being reissued as a 2-pack with Ravage and Laserbeak), is that they will have a slightly different deco to match their original cartoon colours.
I hope that is true, as I'd love to have a cartoon coloured "blue one"... and I'd be okay with having it called Rumble on the pack, because it would be an anime-accurate toy.
(cartoon Frenzy "the red one" we didn't see much of, so if it had much of a different colour scheme to the toy, it probably won't stand out as much)
