As Pxtl said, if you want to work on re-doing OTA models under new designs, CA is looking for modellers!
We cant make direct remakes or copy the PSG TA stuff because they're both copyright. However, our designs has been 'inspired' by some of Arnes work. If we were to draw direct paralels though, we'd probably swap the Arm and Core designs around, so that Arm is the smooth black-and-white one, while core is the blocky one with metal textures.
For Core (Logos, working titles) we are following Mr.D's remakes, which still use core logos and some are based on OTA designs, but are of high quality, good design, and there are enough of them with enough differences from the OTA origionals to create a solid base from. The look is angular, industrial sci-fi.
For Arm (Nova) we are using more anime-esque smooth modern sci-fi designs. The best (though not final or authoratative) example of this is the Spherebot, IE the Peewee Warrior and Jethro replacements.
You can find some of my brothers concept art (mostly for the core AK, so appropriate)
here.
If you'd like to make smooth, curved units, as i say, we've plenty of room for them in arm (nova) if you'd like to work with us!
