Polygon are reporting that publishing giant NCSoft has revealed during a recent earnings report that an expansion is currently underdevelopment for ArenaNet's Guild Wars 2 MMO.

During the earnings conference call the publisher confirmed that the developer is "preparing an expansion pack" despite recent reports suggesting that wasn't the case. As early as March of this year ArenaNet suggested that while an expansion was on the plate for the future, no such thing was currently being developed. No other details were revealed.

According to NCSoft's earnings report, Guild Wars 2 made up 21 percent of sales during their first quarter of 2013, with the original Lineage making up 28 percent. Aion was listed at 16 percent and Blade and Soul made up nine percent of sales.

While Guild Wars 2 might be seeing an expansion sometime soon, the team at ArenaNet are continuing with their live content updates with the launch of the Secret of Southsun earlier today. The new content will have you partner with Inspector Ellen Kiel of the Lionguard as you try to uncover the source of the mysterious animal attacks on Southsun Cove.
