I have mentioned before XCOM will release an update this year, but I was wrong on mentioning it's just a DLC before on my blog http://philgadgames.blogspot.com/2013/09/xcom-enemy-within-dlc-not-expansion-is.html.
But, it seems like DLC to me since I have the PC version, and the only way I can purchase the expansion is thru steam, which by the way, they still blocks my IP address since someone in our IP block merited to be blocked and in the process also blocked everyone else with the same masked IP.
Currently released, here in the Philippines as mentioned by DataBlitz... fingers crossed that I get one later.
