Jack Tretton is the president and CEO of Sony Computer Entertainment America, for those of you who may not be familiar with his name. During the E3 2011 expo, Mr. Tretton, along with Kaz Hirai, talked about upcoming titles such as Uncharted 3 and Resistance 3. They also presented the PlayStation Vita to the world. In an interview with Forbes, Jack Tretton discusses how he and his company are not afraid of competition and are ready to back Vita throughout. Here is an excerpt from the interview.

When will you start talking about the PlayStation 4?
.
PlayStation 3 is really just hitting its stride. And technologically, I don’t think it’s possible to provide any advancement beyond what we have. What we’ve seen from the competition is trying to add features that already exist in PlayStation 3. We invested heavily in that, we rolled a very heavy rock up a steep hill, through the launch period. But now I think that all pays off, and we’ve got a long run way behind it. So, I wouldn’t look for any discussion of a next generation PlayStation for quite some time.
.
I think there’s ground to be carved out for everybody. But I didn’t see anything about Nintendo’s announcement that said ‘Oh, we’d better get working on rolling out a new PlayStation here pretty soon.’
.
Our attitude is kind of ‘welcome to the party.’ If you’re looking at being a multimedia entertainment device, if you’re looking at high def gaming, that was 2006 for us.
