As you may recall, 15 November 2013 was the the release date of PS4, XBO came a week later. Now I'm not saying that these consoles will release on those days, but it's the same ballpark that these next gen consoles will release.
However by this point at least, we got word of pricing, back in 2013 it was on June 10th for XBO and PS4
Both sides are scared to release the price, especially during these tough times, or are they just waiting it out, it's hard to say but who do you think will blink first? Sony or Microsoft?
