The colours do seem more vibrant (that isn't quite the word but I don't know what is. They, like, PING at you.) I was (still am) fond of the fancy borders but it is nice to have the images larger. To those who worried about the card stock - well, I like it.
They do indeed ping. I feel I can really step into them, now that they are borderless ( not that I dislike the borders on the first edition ; it's just a different effect ). And the colours on some of these cards are really deep too. I love the darkening sky in the High Priestess and the Seven of Wands, and the Devil card makes me gasp, it is very immediate, almost like I was one of those cats myself.
Last evening I did a card-by-card comparison of the first edition with the gold edition. Today I hope to do a reading with the new cards, break them in, so to speak.
I have a mental picture of people all over the world receiving these cards in the mail and going through them one by one, oohing and aahing. A global lowering of blood pressure.
