The Sony PS4 is officially launching on Friday November 15. Many stores are hosting midnight launches of the Sony PS4 including Best Buy. You can head out to a Best Buy store tonight and pick up your pre-ordered PS4 (if you got one filed months ago) or try to buy from the limited inventory of PS4 consoles that Best Buy stores will offer. Note that Best Buy stores will take pre-orders for the PS4 already two hours before midnight. Arriving at a store at midnight will be too late.
It also looks like that Best Buy will sell the Sony PS4 console online at midnight. The PS4 is featured on the homepage and marked as Coming soon. Best Buy offers the $399.99 PS4 console and the $569.96 Sony PS4 bundle with Call of Duty: Ghosts and 12-month of PS-Plus.
The Sony PS4 console is limited to 1 per customer.
