Just though I'd inform the general public, about this information. BTW, you should thank DMX for informing me.

Just finished making a mono Dark deck..
I tell you man, sticking to 40 cards is now tough.

Hmmm, thanx for the info, yea as more and more sets come out, it will be harder to specify your deck to 40 cards because there will be so many more cards to choose from.
