I'm concerned for Storybrook. Because, while on the upside, everyone is now aware of the curse which will no doubt help Emma....
Rumplestiltskin, Regina, and the Mad Hatter all kinda hate each other right now.
Rumplestiltskin, Regina, and the Mad Hatter all are gonna have magic back.
With the exception of the fairies (who do not have their fairy dust), none of the other characters really had magic of their own even in the fairy tale land.
So I suspect everyone is pretty much going to be caught in this war between the three of them (though, granted, the Mad Hatter's magic is pretty specific and only has to do with the hat) while trying to figure out why they're not back in the fairy tale land themselves.
I also predict that, with his memory of the fairy tale land back, Prince Charming is hopefully going to be less of a jerkface.
