After watching the series finale I thought of a theory that would maybe bring Juliet back for the season.
When Juliet smashed the rock into the bomb causing it to explode everything turned white, including the Lost logo. I reckon that this whiteness could be very similar or the same reaction to what happened when Desmond turned the fail-safe key.
So maybe the fail-safe key, that Desmond turned, detonated a nuclear device. It was a nuclear device because the Dharma people, including Dr Chang, knew that the nuclear device was thrown down the shaft, which eventually stopped the magnetism after Juliet detonated it.
This could be so as there wasnt anything left of the hatch after Desmond turned that key.
This could be the reason for Juliet to be back next season, just the same as Desmond came back after turning the fail-safe key.
