The Playstation and Xbox got DL content, but is there any for the PC version?

I believe they said that the content from the DLC packs was put into the launch version for the PC.

I would look to see if certain upgrades are available, thermobaric warheads for JSF gunships and anti air guns for russian tanks are the first two to come to mind.

There were 2 maps as well, Cosmodome or something and something strategic reserve...sorry my memory is fuzzy.
