Nope, none of that. The reason the Dinobots, Starscream, and the rest were not in the initial listings is because they are all coming out in June and July instead. Like Hasbro, every toy is being released individually. There are no Combiner Box Sets and Dreadwing and Blackwing are being released under those names. For now, looking at the fact that these are being released individually and with the same names as Hasbro's Power of the Primes toys, the safest bet is that these will also be identical to the Hasbro releases (pictured below). This fits with Takara's recent confirmation that this year will have a brand unification like never before.
Here are the upcoming releases for Takara's Power of the prime line according to S.T.F.U.'s Facebook page.
