People are looking at this in the wrong way. This isn't going to be releasing in the hope people buy a PS4/Camera/MOVE, it's releasing to people who already have the PS4/Camera (MOVE is optional). It may shift a few PS4s at some point but that's not the aim and the reason Sony are positioning it as a product in its own right. You wouldn't see a Blu-ray advert ending with 'TV not included' and it's the same here.
The PS5 Exists.
