"With Sony continually pushing their gaming credentials and the development of the PlayStation brand for gamers throughout their presentation - it has very publicly slapped Microsoft across the face," said Alex Simmons, UK Editor-in-Chief of gaming news site IGN.com.

Vita lives on
In addition to the PS4 news, Sony also talked up the PS Vita.
It has previously acknowledged that the handheld console's sales had fallen behind expectations.
But at E3 it stressed the machine was still "just beginning its life cycle".
It said that 85 titles were coming to the platform this year including Batman Arkham Origins, Killzone Mercenary and a new episode in Telltale Games' The Walking Dead series.
It also described the Vita as "the ultimate companion device" to the PS4 since the handheld can stream the bigger machine's titles.
