Zap2It is reporting that Horatio Sanz, Chris Parnell and Finesse Mitchell will not be returning to Saturday Night Live next season, and we'll assume that's true, though the only one we can be absolutely sure about is Sanz, who left a message on his MySpace page yesterday saying he would be leaving the show:

Hi my Dear fans and friends alike,
I have decided to not return to Saturday Night Live this season. I wish the best to everyone at the show and expect them to have a great season. It's been a wonderful eight years and I am grateful for all the friends I was able to make and all the great people I had the pleasure of working with. I want to give a big thank you to all my fans for your kind comments and well wishes. I look forward to making you laugh in the future, and hopefully not behind the counter at Burger King. Goodnight my dears!
XO,
H

Whether "I decided to not return" means he did this of his own volition or was coaxed to leave is for anyone to surmise, but the bottom line is that he ain't gonna be on the show no more.
