While Call of Duty: World at War’s DLC on the 360 may have set new sales records and surpassed some ambiguous high water mark, it isn’t available yet on the PC. Why? JD_2020 explains on the CoD forums:

Hi all,

The Patch (and DLC) is not releasing for the PC this week. By now you’ve realized the patch did not come yesterday as the rumor claimed. I am not sure exactly where the rumor started, but as always if you didn’t hear it from me, and I am not confirming it, you should take it with a grain of salt.

We have not yet posted an ETA for the patch or the DLC – we are still working some things out behind-the-scenes and do not have further information at this time.

When we do have more information, I will be sure to provide it. There have been requests regarding which “Phase” of the patching process we’re at, but we are in a different process this time around where DLC is releasing hand-in-hand with Patch 1.4. As such, there are additional steps that are unique to this update and therefore override the standard delivery timelines. I will not respond to requests for specific dates — there are many factors outside of the control of the development team, and I can only speak to those parts of the process that are within the control of the development team.

Regards,
-JD

Basically what JD_2020 is saying is that it’ll be done when it is done and your tears will only cause his cold metal heart to rust and release the content slower. I’m not sure how we can complain as we’ll probably be getting it for free.
