Mass Effect 3 Multiplayer DLC Coming?

A rumour has surfaced that Bioware's next DLC release for Mass Effect 3 will be centered around the multiplayer aspect of the game. According to the above image that was released, Bioware will be releasing new character classes. The image shows a Batarian Soldier, a Geth Infiltrator, Geth Engineer, Krogan Battlemaster, and a Batarian Sentinel. This image as of right now has not been confirmed by Bioware or EA at this time, so this is all just speculation that the image is indeed real. However, Bioware did promise multiple DLC released for both single player and multiplayer aspects of the game:

"We're going to be shipping with a pretty impressive array of different things you can unlock... but we're also planning on expanding that over time,"

With how pissed off people are right now at Bioware over the DLC issue, I think it may be wise to wait a month or so to release any new DLC. However, apparently fans would be open to new DLC right now as long as it changes the ending of the game. As there are around 14,000 people petitioning Bioware to change the ending of the game through DLC. Bioware has always prided themselves as a company that listens to their fans, so it will be interesting to see if they bow to the fans pressure and create a new ending to the game through DLC.
