The delay in releasing new DLC for Battlefield 3 is due to the team needing to recharge its batteries following the grueling run-in to launching the main game, according to a member of the development team.
A Reddit post from DICE's Alan Kertz, picked up by MP1st, explained that it took time to ramp up development again after the post-launch lull. What's more, the studio would rather take its time and ensure a quality release rather than rush something out quickly.
"The big reason that '[DLC is] taking so long' is that we pushed hard on BF3, and lots of developers pushed vacations, parental leave and other things for a while to ship a product they could be proud about," he wrote.
"After that was done, it takes a while to get people back into the office and up to speed.
"Better from our perspective to wait a bit on the DLC and deliver quality content with plans to deliver different types of content for different types of players over the lifetime of BF3, rather than hurry one map out."
The FPS sequel originally launched back in October, closely followed by the Back to Karkand map pack. The next expansion, Close Quarters, is due out some time in June, with two more add-ons to follow.
