I will point this out to you, since you fail to have been able to figure it out on your own.
What has been released today are the multiplayer maps. That is but part of what was promised to people who had previously paid full price for NOLF. We were also promised the new single player mission. That has not been delivered yet, and Sierra has been unabble/unwilling to sday whether or not they are going to release it.
Do you get it now?
