I'm surprised there isn't any threads on this at the moment, but they've announced the second expansion of the year in mid-October for the past three years so I'm hoping we'll see something of the nex...
I'm OK with no Expansion Pack as long as the Base Game Updates are worth it. I'm talking about better babies, cars, whim overhaul, personality overhaul, etc. Those are all good updates and will change the way I play the game. Those are worth the wait.
However, if it's just some shallow cosmetic update (500 new swatches of trash cans), then I'll be very disappointed.
