Large games and hardware retailer GameStop has announced at the end of last week that the recent motion detection peripherals, Microsoft's Kinect and Sony's PlayStation Move, are both big sellers and that it's having problems keeping them in stock.

GameStop held its earnings call last week and, in between its impressive profit figures, has also revealed some of its experience with selling the Kinect and the Move peripherals for the Xbox 360 and PlayStation 3, respectively.

Speaking about the Kinect, the large retailer said that the device is in strong demand, and that Microsoft is still managing to meet that demand by shipping lots of units across its retail chain.

"[Kinect] continues to have very strong demand, and fortunately Microsoft has been able to meet that demand," the retailer said, via Industry Gamers. "So we have strong demand, good stock, and we continue to see strong sell of the unit. Attach rate is where we anticipated it would be. We also just got back from a meeting with all the publishers... and most are developing games for the Kinect platform. We're happy to see that there's strong support for the Kinect platform."

While we already knew of the Kinect's popularity, which earned it the title of the fastest-selling electronics device in the world, the PlayStation Move is also fairing pretty well, according to GameStop.

The store chain said that it was also having problems keeping the Move in stock because of the large demand for it.

"We have struggled to stay in stock on the Sony Move controllers; there's a tremendous amount of demand for that," said GameStop's Tony Bartel to IG. "Provided we can get more into stock, we should see some strong growth there as well."

While Microsoft is flaunting the sales figures of the Kinect, which broke past the 10 million units sold barrier earlier this year, Sony hasn't been revealing all that much about the PlayStation Move, limiting itself to saying that it shipped over 4.1 million units around the world.
