Same for me as far as the multi-player aspect. I'm playinging through CoD single-player to get those achievements, but as soon as the new VIP map-pack comes out, I'm eBaying CoD...I don't even need to wait for the Vietnam Map pack.
According to their website, the Xbox & PC should get the update between today and tomorrow (it actually includes all the files for the new map-pack and Vietnam), so hopefully we'll get the new map pack sometime this week.
