What bonus content is available for Simcity?

I have a developing interest in the new Simcity game coming out next month, and I'm starting to poke around to get a sense of things.

I notice that if I preorder from Amazon, I get a "Heroes and Villains" pack.

I've also heard rumblings about bonus content in a Digital Deluxe edition. Are those two items all there is, or are there other preorder bonuses from other retailers floating about?
