Update: What seats are still unconfirmed on the 2019 grid?

With the new signing of Robert Kubica being confirmed yesterday, there aren't a lot of open spots left anymore on the 2019 grid; two, to be exact. 

One of those open spots, the one at Force India, is going to Lance Stroll even though it hasn't officially been announced yet. The team is just waiting for departing driver Esteban Ocon to announce his plans for next season before they announce Stroll. 

The other team who still have a driver to hire is Toro Rosso. Daniil Kvyat has only been confirmed there, with the Russian making his comeback at the team after a year of absence and doing sim-work at Ferrari.
