I've seen the recent letter from Sims Team. I'm really glad they did it, just as I've mentioned in another thread this should help to understand what to expect from Sims 4 development. So the letter itself was a very good and useful move. Now I can personally decide for myself if i like their direction with the game. And I don't. The matter is not the every tiny specific feature - representation or bunk beds or babies... And especially not the new EP to get us excited (though it was enough for many). People are complaining that new addons are shallow and not deliver and get a response in the form "fine we hear you we'll soon announce another one"...
Take time, we can wait. Make your addons meaningful. Fix the core and the bugs! Until then I'm not touching TS4 (anyways it's not in an enjoyable playable state right now) thankfully I still have TS2 and TS3.
