The thing is...at the moment, the PS3 is the cheapest blu-ray player on the market....once costs for production on the player start to come down....surely Sony will be making less of a loss per PS3 than before.
On top of this, they need to reduce the cost, it is just too expensive and realistically it need to come down to £299 at the most for Xmas this year to have a good chance to recoup some of the lost ground with the 360 and Wii.
Prediction (June 12th 2017)
Permanent pricedrop for both PS4 Slim and PS4 Pro in October.
PS4 Slim $249 (October 2017)
PS4 Pro $349 (October 2017)
