Will this be the last year of the Osborne lights due to a possible Cars Land in Hollywood Studios?

Disney Parks has chosen to keep Cars Land exclusive to Disneyland, so it will not be coming to Hollywood Studios. The areas that would have been needed to make that transition to Cars Land possible are not being changed. No, this is not the last year for the Osborne Spectacle of Dancing Lights. To confirm this decision you can look at the Back Lot Tour. Disney just spent many thousands of dollars to make redesigned ride vehicles for Back Lot and they would not have done that if they were going to scrap the ride this next year.
