Not sure how to present this other than say it's a rumor that comes from AutoSpies – make of it what you will:

One of the coolest features of the MINI is the huge panoramic sunroof…the only problem is if you get one with a white roof there is a huge piece of black tinted glass in the middle of you white roof.

MINI will introduce the solution for 2005 model year cars…they have been able to manufacture a panoramic sunroof with a top layer that is white frosted glass…similar to an iMac.

That way, when you look at one with a with roof, the panoramic glass roof will blend in and match the car better.

We also hear there will be a real headliner available next year (not just a mesh roller screen) for those in hot climates who don't want any light to come into the cabin from the roof.
