All five Dinobots. And To a lesser extent, Thundercracker and Skywarp to go with Starscream. Otherwise I really couldn't less if they make other FoC toys or not since the ones that have been shown mostly look like shit.
Slipstream. Just. Slipstream. Well okay, and Demolishor, and Scattorshot, and Arcee, and Air Raid, and the Pea-Headed Dead End (I mean, DAMN. His head is... Just... WOW! But he's still wicked looking)
Slipstream and Arcee X10. Also I'll put in for the Dinobots, maybe a Springer if possible. voyager Megatron with some hands that can hold 5mm weapons, dammit. Deluxe Aerialbot combiner team would also be a nice surprise.
