I'm not sure how I made it until 9 p.m. yesterday without knowing the new Orange is the New Black trailer was out. But, a day late, here it is! Season 3 will be released on Netflix on June 12, so just go ahead and cancel any plans you had for for the rest of that month. 
Rolling Stone did a nice write up, if you're looking for reminders about where this season is picking up:

When fans last left the popular Netflix original series, Piper (Taylor Schilling) had found a way to get a freed Alex (Laura Prepon) back into the system. The trailer proves that Piper's plan worked as a bruised Alex returns to Litchfield.

In true Orange Is the New Black fashion, the preview veers from tense and emotional to darkly comedic. Red (Kate Mulgrew), who spent most of last season butting heads with her old partner Vee (Lorraine Toussaint), seems to be in much brighter spirits following her rival's run-in with another inmate's vehicle. "The world is better in black and white," she tells Piper. "And Red." Meanwhile, Crazy Eyes (Uzo Aduba) is seen explaining to a guard that the story she wrote is not pornographic. "It's not just sex," she protests. "It's love. It's two people connecting. With four other people and aliens."

Annnnd, I need to start rewatching the first two seasons now. Carry on without me.
