I think people are seriously underestimating a permanent price drop for the PS4. Look at all of the people lining up out the door in South Korea with their recent price drops. If you look at the last two Black Friday weeks in the U.S.- PS4 easily beat the competition and sold out everywhere. If Sony had provided more stock an extended the $199 promotion through December- it would have been an absolute bloodbath.
The problem is it's not guaranteed sony will make a permanent price drop of that size. Maybe €250 price this year then €200 for the holidays. Then next year €200 permanently. I hope they are more aggressive but they are clearly going for profits.
