Demand is "strong" for the PlayStation 4 says the president of major US retailer GameStop.
Over 600,000 have signed up for the mailing list to be the "first to know" of any new information or preorder listings for Sony's next generation console.
"With only a glance at the PS4, gamers are excited and eager to know more," said GameStop president Tony Bartel.
"Within just a few weeks, more than 600,000 people have signed up, showing strong demand for this new console."
The PS4 was officially announced last month at a media event in New York City, so Sony is understandably pleased that so many have willingly signed up for something as unappealing as a mailing list.
“The level of enthusiasm we’re seeing from GameStop customers demonstrates how the promise of PS4 is resonating with gamers, and we’re looking forward to unveiling more about the new platform in the coming months,” said Sony Computer Entertainment America president and CEO Jack Tretton.
