I actually didn't actually read the news myself, a friend that's a fellow Jeopardy head texted it to me, so I googled the article and it said:
Quote:
Jennings will host from September until December, a run that includes the inaugural Second Chance competition and the Tournament of Champions.
Bialik will take over in January by hosting Celebrity Jeopardy! and the Jeopardy! National College Championship. Her hosting duties will be balanced with her acting duties on the FOX show Call Me Kat, Davies said.
So I guess that doesn't necessarily mean it's only her for all those months, but I do take it to mean it'll be mostly her. I guess we'll have to see.
