To me personally sounds like Tyra's giving the old cliche answer of "moving on to better things" aka get out or be put out. As a fan of Tyra's it hurts me to say that her show hasn't been the greatest. In 5 years I expected more. Grant it she's on during a time slot when the competition is steep-you've got Ellen at 3 o'clock and Oprah at 4 o'clock. Between Tyra and Oprah's viewers Ellen and Wendy's shows are about to blow through the roof. Not that Ellen needs much help but lets see how well Wendy Williams does with all these changes in daytime talk. Wendy has had a strong come out with her show and hopefully in time the guest will get better (we all know Wendy doesn't have the best rep w/ celebs). The crazy thing is she's more entertaining to watch versus Tyra that does have A-list celebs, larger budget and a much better looking studio.
Kudos to Tyra for stepping down ever so fiercefully. We wish her well.
