There is a lot of news about this coming out still and nothing is saying it will be a full reboot but I'm assuming the last remaining issues before the reboot will have some sort of finality to them to keep people buying them. Maybe all the comics will come to some sort of logical ending?
With all the talk about "The Dark," I hope that each series doesn't end with some silly fade to black a la the fade to white entropy wall that consumed the final pages of each series going into the conclusion of Zero Hour. I hope but, I wouldn't put it past them.
