Last expansions's symbol was a compass; I'm pretty sure this expansion's symbol will be a compass.
How was guilds' symbol a compass?

Thanks. I didn't realize the english word for it was compass.
Native Village cards are face down. I guess you can mistake them for your draw pile if you haven't established a place where you always keep your draw pile, but as long as you can tell the difference between your deck and the Native Village mat, you don't need the actual mat.
You could also mistake them for Haven's set-aside cards, but Haven can act as a mat there (it does in my group).
I guess one important difference is that cards on the Island, Pirate Ship and Native Village mats only matter when the respective card is played - it doesn't really matter if you forget about them for a while. Prince, Haven and Horse Traders shouldn't be forgotten though, as they will trigger without you actually doing something - that's why they better stay in your field of sight.
Cutpurse impacts your opponent's upcoming turn, but no more than any other discard attack. It's definitely not in the same category as attacks that impact their next turn by messing with the top of their deck like Sea Hag, Ghost Ship, Bureaucrat, and Rabble.
Cutpurse was born from the idea to make cards more expensive. It's certainly not the same, but it's the closest reasonable thing to that concept, which is why i put it in that list of non-durations implementing duration concepts. Though you are right, what applies to Cutpurse applies to Militia too. Which makes me realize:
Duration-Militia+$2
All other players start their next turn with only 3 cards in hand.
Duration-Witch+2 cards
Until the game ends or it is trashed, each other player has an additional card in his deck which is worth -1VP and has a coin value of 0$.
Duration-Swindler+$2
All other players trash the top card of their deck. Name a card in the supply that costs the same. Until after the game ends, each player has the card you named.
Edit: Edited to avoid massive edgecasing.
