It was recently reported that Battlefield 3 wouldn't be coming to digital-distribution platform Steam. Though the information came second-hand from financial research firm Baird--and not from DICE or Electronic Arts--EA has since confirmed that this is indeed true. More information has surfaced today, indicating that Origin--EA's new proprietary digital distribution platform--will be required to play the game.
According to fan site Battlefield 3 Blog, DICE's Daniel Martos confirmed that the Origin service will be required to run the game "if it is bought in retail." While it seems likely that digitally-purchased copies of the game will also require Origin to run, that caveat hasn't been confirmed.
Battlefield 3 is due out for PC, Xbox 360, and PlayStation 3 on October 25.
