All Star Family Fortunes is returning to 45 minute episodes for its new series next year (although the Christmas special will remain 1 hour long), and there will be 9 regular episodes, which suggests to me that it is going to be in the Dancing on Ice sandwich next year (as DOI is 10 weeks long and the final is feature length) in a schedule like this:
18:15 - Dancing on Ice
19:45 - All Star Family Fortunes
20:30 - Dancing on Ice - The Skate Off
21:00 - Mr Selfridge
As for Saturdays, Prize Island has 6 episodes, Saturday Night Takeaway has 7 episodes and Take Me Out will presumably have 10 episodes like the current series. Not sure how many Splash episodes there will be or even when it'll air, although I assume it'll be fairly soon. I'm guessing Prize Island will run in January/February at about 7pm with Takeaway taking over the slot from mid-February. Take Me Out and Jonathan Ross could run alongside them in the 8pm and 9pm hours respectively, and then maybe Splash could take over from TMO in March and air with a Takeaway lead-in. I can't see it running for that many weeks so I guess they'll squeeze it in OK. Off Their Rockers could run at about 6:30pm in Feb/March too, with BGT and My Man Can then airing in April/May (I think BGT will revert to starting in mid-April with the live shows in half term week next year).
