Pretty much the entire Neo line.

 

Magnaboss and Trirpedacus, or just Magnaboss with a Silverbolt that won't disintegrate over time.

 

Any answer that doesn't include Transmetal Megatron is incorrect. Such an amazing figure, completely ruined by GPS.

I own both the Japanese version (which is GPS-free), and the Armada repaint, and I'd STILL give a kidney for ole TM Megs to come back.

Also on the list:

Dinobot
Manterror
TM Tarantulas
TM Optimus Primal
Both combiners

 

Dinobot
Waspinator
Magnaboss
Tripredacus
Magmatron
Lio Convoy
Transmetal 2 Megatron

 

Dinobot, preferably molded without transparent plastic and maybe a deco closer to his show appearance.
Waspinator. Basically the entire Beast Wars cast in all honesty.

Polar Claw
Magnaboss (GOLD PLASTIC BE DAMNED, DO IT IN BROWN!!)
Snapper (especially if they redeco it in Skald’s colors)
Armordillo (had one as a kid, wouldn’t mind getting a new one)
Razorbeast

In the off off off chance they dipped into the Transmetals line, which they won’t because of vacuum metal parts, I’d like to see, again, the entire BW cast in all their Transmetal forms, even if they never appeared on the show in said form, like Waspinator, Terrorsaur, and Rhinox.

As for Japanese exclusives:

Lio Convoy
Galvatron
Magmatron
Mach Kick
Saberback

Yes, I know Magmatron and Saberback were technically released in the US in the Beast Machines line, but I want them in BW packaging and of course Saberback’s BM mold, Striker, was a GPS victim so let’s just do away with that. Besides, I like Saberback’s colors more anyway.

 

Is there any confirmed-ish talk of what's after Iguanus and K9?

I've bought all of them, but i get the impression this line has not sold well, so i'm skeptical about it continuing.

 

Legends Convobat would be nice...

 

I am curious about news of any upcoming figures myself

 

Fuzors silverbolt i just really want one

 

Anyone that appeared in the manga and anime/show.

Esp the super fragile GPS/swirly blue ones like God Neptune and Randy

 

I procured Heinrad during my phase of backtracking and getting BWII and BWNeo figures. He is so much fun. And being a functional clock is cooler. I don't use him as such, but the option is always there.

I wouldn't mind some of the Transmetals or TM2s getting reissued.

A non GPS prone Randy would be amazing!

Oh, and the original 2pk Basics Bat Optimus Primal vs Gator Megatron

 

Dinobot

 

Magnaboss, Tripredacus, and BWN Magmatron are the really big wants for me. But more realistically, considering what Hasbro's been giving us so far, reissues of Fuzor Silverbolt, Torca, or TM2 Iguanus wouldn't go amiss.

 

Anything with GPS (Grimlock specifically) or other fragility issues (RAMPAGE, even the Metals version's chrome flakes)
Tripredacus/Tripledacus
TM2 Cheetor & Dinobot
BWN Blendtrons

Anoff-the-board pick is the Armada packaging-style Dinobots two-packs

 

Armada dinobots!
