Very bad for the highstreet consumer. Expect prices to stay high. More people will have to start buying games off the internet from now on.
If you can wait a few days for the game to be delivered, it's worth it. It's unbelievablt how much of a difference in cost a game can be from High Street to Virtual Street.

Permanent pricedrop for both PS4 Slim and PS4 Pro in October.
