Wait, did Moon Express drop out too? Or did you mean Astrobotics? I stayed at the time where Moon Express did have 2 secured launches to the moon with RocketLab. Assuming Electron is still upgoing, I don't see Moon Express retiring on its own...Nice news for Hakuto. I have great hopes for their rover (and doubts about Team Indus Lander...)
SpaceIL, an Israeli nonprofit, will use a SpaceX Falcon 9 to get off the ground. ... As with other teams, SpaceIL is still readying its spacecraft, which is being built at an Israel Aerospace Industries facility. The team’s launch contract is for a six-month window that extends into 2018. If it can’t make the 2017 deadline, SpaceIL still aims to go to the moon: “We have an educational mission that we are intent on achieving that has little to do with the time frame of the competition,” Lichtenstein says.

I consider the teams flying on Rocket Lab's Electron to have virtually no chance of launching on time, and the team flying on Interorbital's powerpoint rocket to have a negative chance, which is a mathematical impossibility, but there you are.
Really, Team Indus and Hakuto on the PSLV are the only realistic candidates at this stage, however, we don't know what stage the actual hardware is at. Of course, the deadline may just be extended again. I remember reading that they weren't going to extend it anymore, but there may be some kind of loophole they'll use. Either way, its been going on for a long time now, and it all seems to be a bit of a bridge too far. I hope I'm wrong.
