It's a very obvious hole in the toyline! Plus I assume they're important in TFOne (which I hope to see sometime this week lol)

Yeah, it's basically just more "Legacy". The only real difference is that it sounds like "Age of the Primes" is only going to be two years, instead of the usual three. There's a list of almost everything coming out next year, I could share it, but if you don't want it spoiled, that's alright too.
