The PS4 was sold out other countries. If I was Sony, I wouldn't lower the price until after those countries are fully supplied. No reason to match the price in the US just to sell the same ammount World Wide. After all countries have atiquite stock, I would lower the price. I also believe that Sony won't have supply issues during the next holiday world wide, and will be prepared to match Microsofts holiday sales.
