I just spent over an hour chatting with friends about the new cards. For the most part, I'm super excited by them, and don't really miss any of the cards that are missing.
I will say that I'm not a huge fan of several of the new wordings, particularly on Mill. The old "Do X. If you do, do Y." made it clearer (to me) that you could half-complete action X, but you wouldn't gain benefit Y for doing so. The text on the card of Mill doesn't imply to me at all that you can discard a single card. The FAQ entry tells me I can, which is nice, but that's not how the card reads to me.
Overall, though, I'm quite stoked. I have several friends who have been waiting for an improved printing of Intrigue, and now they'll get a bunch of fun new cards to go with it.
