I'd like to ask why the suddent release of the 2 DLC map packs?

Because, soon I suppose, you (Crytek) will be releasing the SDK for the general public/ modding community.
With that said, what makes people from "modding" your DLC maps and make them available for free using the SDK.
I know it's needed the .cry file to be able to actualy change them, but a good enough modder can just replicate those maps. Or is there some legal issues or something that would prevent that from happening?

Thank you for your time.

Don't see any issues with this otherwise they wouldn't leave the levels open to be used in the editor.
