At first I wanted to wait, but then I was fairly bored and decided to play it until the end of episode 4.
I'm aching for the last episode, and enjoying the theories people are coming up on how things will end.
Personally I think Chloe won't remain dead, since Max will surely try to find a way around it with her powers; and her rewind won't go that far in time, since it's very likely the multiple endings will have to do with your choices and a full rewind would invalidade all of them. Though the latest photo Max took was before a major decision (with Warren before the doomsday party), so perhaps David or someone else took a later picture of her, but before Chloe died? Mmm. And as to the matter of why Max would choose that photo instead of a former one, on a crappier playthrough were Kate/Frank are dead, maybe it's the only one she could reach before the tornado.
There is also the notion Max actually did a super rewind after gaining her powers on late friday and we're actually seeing the second time she's living that week, though that would go against the notion it's actually her powers who caused the tornado, since the universe seems to go crazier the more Max uses them.
