A class action lawsuit brought on by EA shareholders over a "loss in value caused by Battlefield 4 issues" is moving forward. The suit by Robbins Geller Rudman & Dowd LLP actually references the PlayStation 4 version of the game specifically.
The complaint alleges that during the Class Period, defendants issued materially false and misleading statements highlighting the purported strength of the Company’s rollout of version 4 of its all-important Battlefield video game series, which had provided approximately 11% of its revenues in fiscal 2012. Based on the purported strength of the Battlefield 4 rollout then underway, defendants issued strong fiscal 2014 financial guidance for the Company and actually increased that guidance on October 29, 2013. The price of Electronic Arts’ stock steadily climbed on these statements, reaching a Class Period high of $28.13 per share by August 23, 2013 and allowing certain of Electronic Arts’ senior executives to sell their Electronic Arts stock at artificially inflated prices.

The complaint further alleges that, on November 15, 2013, the day Sony released its new Play Station 4 (“PS4”) console, it was disclosed that players of Electronic Arts’ games were being subjected to multiple glitches and significant crashes when attempting to play Electronic Arts’ titles on PS4. The price of Electronic Arts stock fell on these disclosures, declining more than 7% from a close of $25.96 per share on November 14, 2013 to close at $24.06 per share on November 15, 2013. Then, on December 4, 2013, it was disclosed through discussions defendants had with video game bloggers that due to bugs, connectivity issues, server limitations, and various other problems plaguing Battlefield 4, Electronic Arts had been forced to indefinitely halt the Battlefield 4 rollout and other projects until the problems with Battlefield 4 could be fixed. The price of Electronic Arts shares declined on this news from a close of $22.34 on December 4, 2013 to close at $21.01 on December 5, 2013, sending the share price down more than 28% from its Class Period high.

The short of it is that EA predicted that Battlefield 4 would do a lot better than it actually did, and the reason it's done so poorly is because it was (and is) a glitchy broken mess.

This lawsuit is different from the other one being considered by Holzer Holzer & Fistel, LLC that was briefly mentioned over a week ago.
