As of right now i doubt that they will be MP soon, the release date is in a
couple of months but they should release it and see if they are any bugs.
Also SP only 1 map could've had 2 or 3 it would have made it that more
interesting.
I forsee COD wont have very many big missions, mostly short. most games that only have a few missions tend to release demos with only 1 map. if they have more they tend to release 2 or 3 maps. oh well.
