Based on the path we are currently heading down, I don't have high expectations. I personally hope they stay away from multiplayer, simply because they need to focus on creativity. By creativity I don't mean change everything that made the series great, I mean make a Sims game that is familiar, but better, bigger, less buggy, and beautiful. If they don't know what fans want by now they haven't been listening.
If they want to go the multiplayer route they should go all in and do a Sims online, so I know not to buy it. Just don't call it Sims 5 and half baked Single player to shoe in multiplayer please.
