SLK Panorama Roof Option?

I love the Panorama roof option. Photos recently hit the Internet of an SLK with a prototype of this option. This is a stunning option on the SL and makes the hardtop convertible experience even better. A great side effect of the Panorama roof is that the black glass roof gives most cars a really nice look. The S-Class and E-Class with this option are great examples of this. The car that would really look great with this option is the CLS. It would probably hurt back seat head room though...
