The corresponding drawback of trying to reap the business benefits preorder and hype-wise, of an overly ambitious or misleading (intentionally or otherwise) vertical slide demo or trailer is the backlash and loss of consumer trust when you under-deliver or cut back. It can often be really hard to make a demo or trailer that isn't a mess without polishing it as much as possible. Development is messy. But sometimes you really can say "that's a lie" or "no, it [game feature] won't do that" and those ones beleaguer the benefit of the doubt. It's a tough problem.
