Hmm... These are what I would want to see:

-Shockwave (With the movie popularizing him, i really hope Hasbro finally makes this guy)
-Blitzwing (not sure if Hasbro would do it knowing their policy)
-Sunstorm/Skywarp re-release with proper deco following gen TC.
-Trailbreaker (Legends foreshadowing)
-Hoist (remould of Trailbreaker)
-Arcee

Continue Deluxe/Scout sizing minibots
-Brawn
-Beachcomber
-Skids
-Gears
-Huffer
-Powerglide (I can dream)
