I think the main reason "Queer Eye" ended is because all those guys have their own individual projects going on now.
Ted has written a couple of cookbooks and is a regular judge on Top Chef, Carson has the fashion show "How to Look Good Naked", the designer has his show "Dress My Nest", and the young guy is doing fashion red carpet reviews and can be fouind on lots of different shows.
The only one I don't see a lot of is the (really cute) hair designer. I keep waiting for him to pop up on "shear Genious"
(Sorry I forgot most of their names - its "brain down" day today)
