If you look carefully at this photo. it looks like his skis have Cap construction just like his 07-08 Dumonts but only with next years graphics.

Compare it to the next years sidewall construction here, you can see that the graphic ends where the sidewall begins rather than continuing to his edges.

BTW, this id FAR from being a blame or whatever on Dumont because to do such a crazy thing, it is normal to use skis that you are 100% used to rather than totally different skis only to please your sponsors.
And also I might be wrong and maybe your eyes will see something else but it looks very plausible from what I've seen on the pictures.
