New info,which can be consider as bad news.
From
this article published today by Gamasutra MW3 will be launched with a paid based service called "Call Of Duty Elite",which is an additional extra payment to existing online gaming services(XBL,PSN),what they say is that portions of the game will be unlock in the disc,while DLC packs will be available for download with a monthly subscription service, according to the article the price of the service will not surpass the 8.00 USD mark.
However,I think that is some kind of abuse against loyal customers,I know that MW games are good and online is popular,but is not so much to pay for for maps and perks,I know that B4F uses the same scheme but they offer the game free,while here the game is offered at retail price.
So,is pathetic really,but it was coming since a year or so,wait for confirmation from another source thought.
