EA has already launched an Origin page for its new SimCity, revealing that those picking up the Digital Deluxe Edition will be getting a range of content that includes supervillain lairs and European city packs.
Those buying either the Digital Deluxe or Limited Edition sets will get access to a range of superhero content, including a superhero and supervillain themselves (the game has individual Sims, so they'll appear in-game), along with their relevant buildings (or lairs) and special events (the villain goes on a crime wave).
The Digital Deluxe version alone comes with three themed packs to let you build British, French and German neighbourhoods.
Interestingly, the Origin page also has a bunch of system specs, as well as mention of up to 16-player multiplayer (how that works with the announced "Social Flow" isn't quite clear). Those specs are below.
AMD Athlon 64 X2 Dual-Core 4000+ or better or Intel Core 2 Duo Processor 2.0GHz or better
Windows XP: 1.5GB
Windows Vista and Windows 7: 2GB
