450R front suspension

Sorry if this is covered, I didn't have time to search any more and could not find it yet.
Somebody has to know if the a-arms for a 400ex are going to fit, or if it is 250R a-arms, or if it some new design. I would like to order a set so I have them when the new quad arrives.
Thank you in advance.

I believe the company that would know this would be Roll Design, since it looks like they have had their hands on the bike already ;)
