^^ I like how these guys think.
1: More fembots.
Nautica for sure.
(Large) Voyager or Leader-class Strika.
Legends-class Nickel of the D.J.D.
Deluxe-class Classics/Generations-style Airachnid. Done right - or at least less horribly wrong - this time.
2: Legends Kickback and 3-pack Sharkticons.
Also Combiner Wars Deluxe Sweeps, to serve as limbs for Galvatronus and/or as additional Sweeps. Really, just more army-builders as case-filler figures in general.
3: "Disguise" Bumblebee. Instead of doing endless Bumblebee repaints, how about giving us one Bumblebee per line in a 'disguise' theme with alternate (and easily-swappable) heads representing Bumper, Hubcap, and Goldbug (and/or other Bumblebee-ish figures), so we can turn some of those excess 'bees into (whatever)-verse other characters? Hell, just make the heads easily replaceable and release a few alternate heads at the same pricepoint as a Legends figure - it'll still be better than New Hat Bumblebee in Wave 2, followed by Hot Date Bumblebee in Wave 3, followed by Gone Fishing Bumblebee in Wave 4, etc. etc.
4: many, many others. Too many to name them all, but two that stand out are:
Titan-class Unicron and Primus.
I'd love a Titan-class Predaking too, but really...if anyone deserves/needs a huge toy it's Unicron and Primus.
