PS4 has "three advantages" over Xbox One

The PlayStation 4 has "three key advantages" over the Xbox One, according to Sony Computer Entertainment America president Jack Tretton.

The war of words between Sony and Microsoft has been hotting up with the next-gen console launches right around the corner.

Tretton is the latest to have a dig at a competitor, claiming that the PS4 trumps the Xbox One when it comes to power, price and line-up of games.

"[There are] three key advantages," he told Fox. "We've got the most powerful machine on market; $100 USD cheaper than our competition; and most importantly, the biggest, most diverse exclusive line-up of any platform ever launched, and that's what's really doing to drive the sales of us in the long term."

Tretton added that there will always be competition but Sony is focusing on consumers.

"And we see competitors come and go. We've had formidable competition in the past, we'll have formidable competition going forward.

"You get laser-focused on your business vision and you execute what the gamers want."
