German computer-games investigators Gamestar got a chance to talk to EA's Patrick Söderlund, and you can see that interview embedded below. It covers a number of issues, but most tellingly reveals that DICE have no current plans to produce modding tools for the game. Söderlund claims that that modding would be "very difficult" due to the complexity of the levels and features like destruction.
Ah, yes. The modding community: famously confounded by complexity and difficulty, only able to get their heads around the simplest of game technologies... But seriously, not producing modding tools is surely going to be a commercial decision, and I almost wish that were the reason given.
