i was thinking that IW could do what Eidos Montreal did with DEUS EX and make a DLC with missions. it would start 1.) sandman, grinch and truck's last stand in the mine. 2.) Then go flashback 2013 when sandman, soap and the rest of TF141 do what they did in the video of operation kingfish.(although i never understood how price was there?) and then will finish with a cutscene of price being taken to the gulag (maybe)
it is 2 missions so it would be about 400MP for both.
or it will recount yuri's time with makarov and the ultranationalists
dunno how that one would work? but you never know what will happen
