The excellent Sci-Fi show 'The 4400' was canceled abruptly after what some may consider one of the most interesting and open-ended cliffhangers in the series history:
Essentially half of the population of Seattle and some unpopular cast members die from a promicin overdose spread by a "The Naked Time"-like disease. The other half of Seattle and most of the surviving non-promicin powered regular characters gain random amazing powers.
Did René Echevarria or Scott Peters give any interviews or leave any notes about where the series was headed?
Is there any information about what was planned for Season 5?
