Re: Dutch “steelbook” editions of Dominion and Beginning?

I was wondering if the extras on the Dutch “steelbook” releases of Dominion and – yes – Beginning were substantially better than what’s available in other versions. I know there’s some footage from Dominion’s premiere as far as Dominion is concerned, but is that all? As for Beginning, I have no idea if it has any other extras than the R4 or R1 versions… anyone? 🙂
