Well, we know the Needlenose and Darkwing molds can connect Predator-style. Now to see if that actually comes to anything.
I wonder if the desire several of us have for some more obscure stuff is just due to fatigue over the re-re-remake of the same bots over and over. I started skipping even replacing ones that wore out till something really new appeared, which is why my dilapidated old RTS Wheeljack and Jazz didn't get replaced till Origins and I am still using a Classics Rodimus with FansProject armor. Its hard to be excited over something new when it isn't.
I loved the new Dinoking despite skipping the Dinobots, I even want to get some shells if I can to make Pretender Beast style arrangements with them (I hope the core size makes that sort of add-on more likely). Even if I can't do that, with the stock set I will have something totally new to me on the shelf. And nowadays, that's rare.
