Bus <---never had one before. Don't really care about which make or model, just as long as it looks like a regular urban bus.

Taxi <---only ever had a repainted Mini-Con. Again, don't care about make or model - just make it look like a normal taxi.

Chicken (domestic) <---never had one before, and it's the only animal from the Lunar Zodiac who's never been done as a Transformer alt mode

Monkey <---only ever had one done before; Optimus Minor. But it was terrible. You can't even tell if it's meant to be an Old World or New World Monkey, let alone what freakin' species it's meant to be. We've had plenty of apes as Transformers, but not monkeys. I'd personally love to see a Macacque done as a Transformer alt mode.

Sheep (domestic) <--- the closest we had was Ramulus, which as a Transmetal 2 was a mechanical approximation of a wild goat. But I'd like to see a realistic looking domestic sheep, preferably a merino.

Star Upper! <---the Kangaroo Transformer from Beast Wars II/Neo who's never been made into a toy! (see Paulbot's avatar/signature ) He could come w/ a joey that transforms into a weapon. Sure, it'd mean that we'd have a male humanoid that transforms into a female beast mode, but it's not as if that's never happened before!

Koala <--- as also briefly seen w/ Star Upper in the Beast Wars Neo cartoon

Laptop <--- They really should've made DotM Brains into a Scout^Commander Class toy like they did w/ Ejector. Well, I suppose we did have Device Label Blaster... but something from Hasbro aimed at kids!

Android phone <---scary to think that the mobile phone modes of Speed Dial 800 (and his repaints) are now outdated. We need an android-phone Transformer. I'd like to see this toy at 1:1 scale too. Admittedly this would be quite challenging, but if they do manage to pull it off, then why not...

Tablet <--- TF iPads etc.!

Vending Machine <---seriously... where's our transformable Dispensor toy?!

More Nerf guns (but in darker colours) <--- Classics/Henkei/United Megatron was a Nerf Maverick; I'd like to see other Nerf pistols done as Transformers and perhaps released as Classicsverse Shockwave (I'm sure there's a Nerf gun out there scifi looking enough to pass off as Shockers) and Browning. Although hopefully Hasbro won't cover it with "clown colours" like they did w/ Classics Megs, otherwise I'd hold out hope for a better coloured TakaraTOMY version.
