In CEP are includet many of parts of armor that is not including in Q but is it in high quality. And some of creatures like Tiamat dragon.
Q has more than enough armor parts to outfit JC Penny and many of the armor parts overlap between CEP and Q. I'd like to leave some room for Builders to add their own customizations if needed.
Not much desire to add Tiamat either, although its a relatively OK model it would be a step back in styling since the Q chromatics use skinmesh. Also, the animations, from my understanding are quite quarrelsome.
New PC parts - yeah that's highly probable given the existence of packages such as THIS.
