I know nothing about Spacewarp beyond she's a female Decepticon space hauler, but that's enough for me to want one. If she did get a new toy though I'd want it to either be an original mold or retooled enough from a theoretical Armada Jetfire remake that she just looked like a chunky, cuddly fembot and not just a redeco of Jetfire with a new head. Cuddly is fine though- me likey the cuddly fembots.
In terms of holy grails, I have a few.
RID Sky-Byte (the original): Ever since I saw him on the cross-sell for my Megatron I wanted him. Mum searched high and low but never found him. Never seen RID in my life but I just love that toy design.
RID Galvatron/Devil Gigatron: My own Megatron is in absolutely shambolic state, but I love the mold so much I'd kill for a replacement. I kinda fancy the Galvatron deco because as neat as the original is, there is something pretty badass about the white, black and gold of Galvatron/Devil Gigatron. Devil Gigatron would be especially awesome as he has the updated engineering (allowing for all 10 modes) and the much cooler lance designs.
Beast Wars Rampage: This guy was AWESOME in Beast Wars and the toy looks awesome too. A pity he's so expensive complete on the aftermarket.
Cryotek: I know the mold has its flaws (I wish the dragon tail was attached properly) but come on. Big scary cyborg ice dragon.
