Kyle Richards: Leaving The Real Housewives of Beverly Hills?

Last month, we reported that The Real Housewives of Beverly Hills would be back for a second season, with the whole cast returning for all the fun.
Might the second half of that statement have been premature?
Kyle Richards, a.k.a. the gorgeous, normal and happy one (relatively speaking) is now hinting at an early exit from the Bravo franchise, according to EW.

The sister of co-star Kim Richards and aunt to Paris and Nicky Hilton isn’t confirming a departure just yet, but isn't sure she'll be back on it either.
“The show has been picked up for a second season, but I’m not sure if I’m coming back yet,” she said, sending chills through the spines of fans.
While rumors about new cast members (Faye Resnick, Ayda Field) have been flying, Bravo is keeping mum on cast moves and possible additions.
“The only thing we’ve announced is that The Real Housewives of Beverly Hills is coming back for a second season,” a rep for the network told EW.
Would Kyle’s potential absence make you less likely to watch? Is she your favorite, or do you tune in to watch the train wreck that is Camille?
