Spring Disney Crocs Specifics?

[AliciaS]

Other than the general themes such as Pooh, Pirates, Toy Story, Princess, and Cars, does anyone know anything more about the spring crocs?

Is there a date?

Are the cutouts different?

What will the colors be?

If I wait until they come and don't prefer them, will the current Mickey ones tsill be available?

I'd like to buy them by April 1 as we leave on April 28th and want to make sure there is shipping and wearing-in time.

Thanks!
