The fall TV season hasn't even started yet, but we're already thinking about next summer.

We've got almost a full year to wait before Season 4 of Netflix's Orange Is the New Black premieres in June 2016, and the show's stars are being typically tight-lipped about any new developments that await the ladies of Litchfield in the upcoming episodes. But here's 5 things we do know:

1. There's a prison population problem. The central issue that will plague Litchfield in Season 4 is overcrowding, according to several cast members. Guess that explains all those new prisoners who arrived at the end of Season 3! We're guessing the influx of new inmates is going to cause problems when it comes to the living quarters (how many prisoners can fit in one bunk?!), and even more territorial issues in the kitchen. "[The overcrowding issues] are going to carry over to every nook and cranny in our prison, believe me when I tell you that," star Kate Mulgrew tells TVGuide.com. "What [creator Jenji Kohan]'s going to do that no other creator is capable of doing with such expertise is, she's going to make you feel overcrowded."

2. Crazy Eyes may finally get a legitimate love story this season. And more importantly - what would a relationship even look like for Suzanne Warren (Uzo Aduba)? "If she was with an equally yoked partner, I think that it would be very fulfilling," Aduba tells TVGuide.com. "I think she would be in that space of openness and trying to learn. I think that she would be giving of her heart and her mind and her soul, in complete fullness and complete abandon. And that might be pretty, messy, sticky - but beautiful." Based on their sweet(?) game of turtle fetch in the Season 3 finale, it seems like things may be heading in that direction for Crazy Eyes and Maureen (Emily Althaus). "That's my wish for her," Aduba says. "I want her to know that she is loved, and to meet someone who values her."

3. The Sofia/Gloria feud will continue. Don't expect a reconciliation between Sofia (Laverne Cox) and Gloria (Selenis Leyva) to come any time soon - or even at all. "No," Cox says flatly when asked if there's any chance for the two women to shake hands and make up. "I can't imagine. As a viewer watching, seeing how much remorse Gloria has, I always like to believe there's a potential for forgiveness, but this is pretty bad. This is really, really bad." Leyva, however, is more hopeful. "We don't know what's coming yet ... but they are good people, and you see that individually," she tells TVGuide.com. "The audience got to see that these women are having conflict. And it's not about a personal attack on each other. It's more about their children, and how they're desperately trying to hold onto some kind of control."

4. Alex is back - and pissed. By now, the secret is out that Alex (Laura Prepon) survives her attack at the end of Season 3. But after discovering that her suspicions about being a target were right, she'll be returning to Litchfield watching her back, and prepared to strike first against any potential threats going forward. "I don't think you're going to see a more timid side of Alex," Prepon tells TVGuide.com. "If anything, she's justified in her paranoia. ... That empowers her, in my opinion." But will Piper (Taylor Schilling) be by her side going forward? "You can't control where your heart goes, and Alex and Piper will always have a connection," Prepon adds. "I definitely think that if Alex needed her or she needed Alex, they would be there for each other completely."

5. Will we see Nicky again? Neither Natasha Lyonne nor the Orange writers will confirm whether Nicky will return to Litchfield after getting sent to Maximum Security at the beginning of Season 3. But in the likely event that she does come back, one thing's certain: her relationship with Red will be strained, to say the least. "I love her, but you know, you can't do drugs," Mulgrew tells TVGuide.com. "I have no idea what's going to happen., but Red's laid down an awful lot of tough love. What I hope with Red is that we see her develop into a very complicated person. ... I'd like to see her sort of struggle with her own ideas of what is right and wrong, because she's so rigidly right and so rigidly wrong. And it's what lies between those two that makes us suffer."

Orange Is the New Black Season 4 is scheduled to premiere in June 2016.
