Hopefully,
The thing is that game studios don't tend to have people work on larger multiple projects like this, when they are getting ready to release a new game they tend to have something called "full production" which is when everything has been decided and they want to focus on getting the new game done. That's when studios tend to be silent, and if they are supporting other games then they tend to not release any major new content because they want everyone to be able to work on their new game and getting it finished.
When they announced project Rene during the last sims summit and said that they had 2 more expansion packs planned then I guessed that would mean that they planned to support The Sims 4 for at least two more years and after that they would decide if they would go into full production to finish Project Rene.
I know that they have said that they have separate teams, but they are going to reach a point where they are not going to be able to change a lot more and just need to work on creating everything that they have decided to make.
