Sims 3 major update

I would like to know if anyone at EA is planning to release a major update for this game. I have been a Simmer for years, and it is frustrating that the game still doesn't run properly due to bugs, poor optimization, and frequent crashes. EA already released a patch for The Sims 2, so why not do the same for The Sims 3? All Sims 3 players are waiting for a big update
