I got mine, and I love them.
I'm a 4th Edition player / DM, and I'm glad to see that even most of the mechanical effects (those in the black boxes) are "useable" as-is. I only count 10 cards that I plan on changing the text around a bit, to fit better with 4th edition, and most of them are really just changing the language, or subbing in a different status effect or replacing a feat/skill that doesn't exist in 4th.
I love the cards, and I'm glad that they're so compatible
