Meh, someone's gonna take that up if the opportunity presents itself. At least the trailer's still someone else's problem. It's just such an unnecessary budget complication at this point. (And it seems like an easy enough thing for them to engineer and produce and sell for way more than it's worth once the need is there. And if cost is too high or demand for it is too low to justify them making it, well, that just proves that Hasbro shouldn't bother either.)
Now if it were Armada Prime's trailer, or Rodimus', that's something that arguably should always be part of the main release. But the long gray box with minicar (sometimes) seems like something that just isn't a feasible ask at main retail price points, and so much gets compromised to make it happen at all that it ends up pleasing fewer than it should anyway (I didn't mind either ER or SS trailers, but I can see why some might feel underwhelmed, and boy I've certainly heard enough of that). Spend the money on something better. The Classics Voyager was a solid mold and the trailer wasn't missed; those who DID miss it eventually had ones they could get. And the field is fuller now.
