Regarding your questions, I too hope she'll not abandon what made her famous, and talk about food at least some of the time. I think the enthusiasm she has for food, which you described, is part of her appeal (in contrast, I hate the hosts on Food TV who look like they don't even eat telling me what's good in food ).
No, I never read her magazine. Is it worth buying? Is it all (or at least mostly) about food?
