The only difference I can see is the battle damaged one which I will likely never use and I actually didn't notice it until I hit post on my message.Well if you can't see the differences you're probably good sticking with your DX09
The cowl and mouths are completely new - but the body from there down looks identical; if it has a new body with ratcheted joints underneath the suit that would be a huge improvement but we won't know that until the figure releases and people have it in-hand. The cape is also all-new and appears much improved but as you said you've already picked up a 3rd party option so you're good there.
