I honestly think this will be different depending on your choices in 400 Days.
If in Wyatt's story you went out of the car, you would get left behind by Eddie. And in the Epilogue of 400 days, Wyatt states that Vince was the one who saved him, only if Wyatt went out of the car to check on the living person.
If you did that, it will be Vince and Wyatt.
If you DIDN'T get out of the car, it will be Danny/Justin - whoever you saved in Vince's story...if it was Vince and Wyatt, Danny/Justin would be back at a camp scavenging for supplies or whatever, same with Vince and Wyatt..
But what do you think? That's just my prediction. :D
