With all this talk about who's going to die in season 26, I did some research about the clues that have been given. Here's what I found:
Clues:
Al Jean said the actor of the character to die has won an Emmy for playing this character.
The episode is called Clown in the Dumps, and it will be the Season 26 premiere.
The character to die has been on more than twice.
One of the main cast.
Hank Azaria said none of his characters would die; therefore ruling out characters such as Moe Szyslak, Apu Nahasapeemapetilon, Chief Wiggum, Jeff Albertson (Comic Book Guy), Carl Carlson, Professor John Frink, Dr. Nick Riviera, Cletus Spuckler, Snake Jailbird, Lou, Kirk Van Houten, Disco Stu, Sea Captain McCallister, Superintendent Gary Chalmers, Duffman, Rafael (Wiseguy), Bumblebee Man, Drederick Tatum and many others.

Al Jean said because of (RIP) Marcia Wallace's death, Edna would be retired not killed off.

Al Jean said that Anne Hathaway's Princess Penelope character is not going to pass away.

It can not be Homer, Marge, Bart, Lisa, or Maggie because they are all in upcoming episodes.
Julie Kavner won an Emmy for Marge but she is safe.
Nancy Cartwright won an Emmy for Bart, but he is also safe.
Yeardley Smith won an Emmy for Lisa, but she is safe.
Dan Castellaneta has won few a awards for Homer, but he is safe.

His others characters do not count as, they were not mentioned in the nomination sequence at the Emmy's.
