The renewal of Garry Trudeau's Amazon Studios comedy Alpha House means there won't be any new weekday Doonesbury strips until at least fall. New Sunday installments will continue to run for the time being.

The Pulitzer Prize-winning cartoonist announced in May he would take a summer sabbatical to work on Alpha House, a political satire about four senators who share a home in Washington, D.C. New Sunday strips reappeared in September, but daily versions were delayed until November; according to the Chicago Tribune, vacation repeats began running this week.

“As I discovered last year, the demands of producing the show are considerable, and my efforts to return to the daily strip while we were still in production had to be abandoned," Trudeau said in a statement released this morning.

He declined to offer a return date, saying, "There's no way of knowing how many seasons of Alpha House lie ahead. I could be back drawing Doonesbury full-time in the fall.”

However, Trudeau acknowledged to The Washington Post that the break from Doonesbury may have a price: “A hiatus comes with uncertainty, of course: I can’t assume I’ll be welcomed back a year or two from now.”
