I believe the 3D dice rolling 2d10's for d100 is coming in an upcoming update (though no one knows the future, I heard about it being in-the-works). It has been mentioned by some of the Devs somewhere on the forums or Dev blog. There was talk of the two d10's being different colors (like a red d10 & a blue d10). I'm not sure if they said this is coming in the soonest major update cycle or in the future, or still an idea in the works, but I believe it is coming. By the way I don't recall anything saying they'd do this for d1000 though. I tried doing a Forum search to find this statement for you, but it's not coming up clearly. Sadly the Search Results on here are not sorted chronologically (that's another Suggestion for another thread...) and there's a lot of posts about d100 to dig through trying to find where this was addressed by a developer most recently. It was within the last 5 months.
