Yesterday EA published a list of digital retailers which would be selling Battlefield 3 and according to the website Joystiq who managed to get a look at it before it was taken down Steam was absent from the list.
 This comes as no surprise to some since Crysis 2 was taken of the digital store by Valve for apparently breaking the rules on Steam, which is probably EA’s Origin digital shop which went live earlier in June of this year. It does appear that both Valve and EA are still having a mini fight about Valves strict rules and this is leading to no Battlefield 3 on Steam. I have a feeling there will be a few upset people who both like Steam and the Battlefield series.
