New Mass Effect in Development?

A note at the very end of Kotaku's Anthem story mentioned above has a quick tidbit on BioWare's plans for another Mass Effect game. They don't state the source of the information, but here is the almost off-hand mention about a continuation of their space opera that concludes their report:
BioWare, meanwhile, is still invested in role-playing games. In addition to the much-anticipated Dragon Age 4, which BioWare teased last year, a new Mass Effect game is in very early development at the Edmonton office under director Mike Gamble, a longtime BioWare producer.
