For goodness sake people, put your pitchforks down. If you're complaining about a lack of engine switch without any information being released and a lack of the promise of previous bugs being fixed in a 34 seconds trailer, your expectations are too high.
You can presume as much you want but it's all moot until solid features and details are released by EA/CM.
I understand it's your hard earned money being spent in the long term but currently, nobody is forcing you to pre-order, you are not contracted to buy this because you have purchased a previous version, you have spent no money yet. There is very little point claiming that the developers are making you out to be stupid. Maybe it's better not to expect anything to begin with, then your disappointment will be miniscule.
