This is certainly true. It used to not be the case even a couple of years ago, but now it 100% feels that way. The most recent SWTOR 'expansion' is a good example of that. They tried to cram preorders for special goods down people's throats before they had literally given any information on it, then made the duration so short that you had to make an impulse decision to buy it.
They certainly weren't doing their hardcore fans any favors, but they weren't tyring to. They wanted their money now and they got it.
