I don't think anything of thoae will be coming. CAW was just discussed on June(If I recall completely). A simmer made a complete concept of CAW from the UI, features, and functionality. Even the gurus was impressed on the level of depth it has. They knew its coming and posiible, they knew we want it, but I don't think it will come this fast.
Color Wheels would be awesome, but from the videos we seen at SimsCamp, they still use the design tool and there is nothing on the UI that has indication.
I do love the improved personalities, but if they are part of the update, then improved personality is something that we should have all noticed.
An Attraction system is probably the most possible. Its not seen on the simology tab though. I don't think they will put it on the other tabs.
My guess, it is something unexpected like the terrain tools. It is probably a live mode gameplay future that dosen't uses new user interface, kinda like toddlers, say if toddlers are just coming by this update and there is no CAS video shown, we would not know its toddlers because there is no change UI at child to Elder when adding them.
I think its something unexpected.
