Honestly I think it's unlikely but not impossible. They've already stated that this game will go on for a couple more years and they seem to be more open to hear us as time goes by (providing things like terrain tools and plain white/black doors). I think they are aware of the problems with Sims 4 and they want us to enjoy de game (cause $$ with more DLC) so I think they will try to solve most of the issues we're pointing. Of course, if you're asking for open worlds or color wheels, I say give up, but I do believe they can do a personality overhaul, add cars and solve minor issues. At least I hope so.
