Jay Leno regretting retirement announcement?

Recently it was said that Leno was going retire and that NBS is going to hand over the reigns to his late night show to Conan O'Brien. Leno I guess is upset that Conan will be given the show. I'd rather watch a show selling diamond rings than to watch Leno, but apparently he is the most popular late night show there is. A recent poll on AOL says that both Leno and Letterman are more popular than Conan. I find this utterly ridiculous. There is no way that anyone in the 18-40 market would rather watch these 2 has beens over Conan. This is what NBC was betting on when they decided to try and keep Conan here when Leno retires in 2009. Leno agreed to Conan replacing him so that NBC could keep him at the network.
