It is expected that they will FINALLY announce their drivers for 2015.
Assuming they announce Fernando Alonso, the biggest debate is if they retain former World Champion Jenson Button, or go with his younger team mate from this year rookie Kevin Magnussen.
Other than that I think all the teams have announced their drivers for next year, minus of course Marussia and Caterham teams that we won't see racing again.
And of course there is still some confusion at Sauber, after they announced their two drivers, but then two OTHER drivers claimed they had contracts for next year also. Not sure that this one has been sorted out yet!
F1 in 2015 will then likely end up with only 9 teams, 18 drivers, and we'll see the return of Mexico City on the schedule, with the mystery and intrigue of Korea being back on the tentative schedule for now, but likely to not happen.
Racing will start again in March in Australia, and between now and then we'll get to some on track practices in February too.
