If the others run a new show or not, I honestly don't think it will effect the viewership of Letterman's last show one bit. Lines have been drawn long ago, in the late night talk show world. The Letterman fandom will tune in, the haters won't. Good thing Kimmel is doing regardless, though I don't think he would have stolen a single viewer.
