I had the same reaction that you did, OP. It seemed exactly the kind of 'hint' that EA would accidentally drop, on purpose.
Yet, these days, I prefer to err on the side of nope, rather than hope. That way, I am no longer disappointed by EA's lack of follow-through on most of the things that have to do with the Sims themselves.
Who knows? Now that the staple themes of the franchise have been added to TS4, perhaps the development team will finally begin to focus on fleshing out the different life stages and the Sims' personalities. That would go a long way in encouraging me to actually play the game.
