Here is the latest news on the MA downloadable content directly from the DLC Producer. This was posted in the official MA forums over at Xbox.com.
"Hey All,
Just wanted to let you know that the first batch of DLC has completed its test pass and is currently in the XBOX official certification process. That means you should be seeing the new maps and 'Mechs any day now (my guess is by the end of next week). Since you waited so long we are going to combine the first four packages and release them all at once instead of a couple a weeks apart.
Thanks for waiting, I know it's been tough.
tj"
Wow the first four packages? That sounds pretty hot!
