OP might have a point considering lot's of people in this thread raising denial about it enough to grasp at straws by comparing the price of DVD players to the price of a PS2 in different regions ...
I would say DVDs only significantly contributed to the PS2's early lifetime for at most 6 months, claiming anymore than that is fairly disingenuous as time continued on the price of DVD players are more than competitive in comparison to the PS2's price point ...
The PS2 wasn't being sold early on solely because of the DVD playback functionality so much as it was riding on the success of the PS1 ...
DVDs also didn't get wide spread traction until well after the launch of the PS2 deep into it's life where new games became the selling point ...
