In a video posted on the programme's website, Cherry also suggested that the episode is the show's best ever season finale.
"I can promise you we've got some old faces from the past returning in the season finale," he said.
"[For] some people it will be their last episode. And I've got a great little cliffhanger question that's going to hang out over the series over the summer."
He added: "It's really, I think, going to be one of the best season finales we've ever done."
The season finale of Desperate Housewives will air on Sunday, May 16 at 9pm on ABC.
