Despite users spending extended time and money in Home, Sony isn't currently aiming to develop it as a marketplace.
During the London Games Conference last night, Pete Edwards, director of PlayStation Home, said that Home users are spending money on items through microtransactions in Sony's virtual world.
"It’s been a long road," he said. " We've proved there is a market out there and we’ve got a lot of people that spend a lot of time in [Home]. It’s not a priority right now but there is a business model there."
Edwards reported during the Develop conference in August this year that European users spend on average 56 minutes in Home per session.
