Looks like Electronic Arts and DICE will be unveiling their hotly-anticipated Battlefield 4 at this year’s GDC in San Francisco at 7pm on March 26th, 2013. The invite reads “Please join us to celebrate a brand-new era of Battlefield”. This could allude to the game being on next-gen systems (which would be expected), or, perhaps it alludes to the game being set in the near-future? They tried this before with mixed results in Battlefield 2142, but it would be interesting to see what they could do a second time around.
UPDATE: Looks like being set in the future is a no-go. AllGamesBeta has found the promo image this invite image is based on below:
