We don’t want to raise any false hopes, because that’s a very awful thing to do… but there could be a chance to have Crossing Lines back for another season or two.

Here there are the interviews with Elizabeth and Goran who talk about it:

Can we expect a season 4?
Elizabeth Mitchell: “I signed a contract for two more years and so did Goran.”

Do you know if there will be a season 4?
Goran: Not yet. For now, we wait. The creative decision has not been made yet, the distribution has not started yet so we wait. “Do I move on? No I have to wait again. OK no problem.”
