Sony UK executive Fergal Gara is not too thrilled that some people are selling their limited-edition, 20th Anniversary PlayStation 4 systems on eBay, though he understands this can't be stopped.

"That's not what we want to see happen," he told Eurogamer about the eBay auctions for the rare PS4s, some of which have sold for thousands of dollars.

Gara went on to say that Sony intentionally only announced where fans could buy the commemorative consoles--with only 12,300 being made worldwide, they are indeed rare--through channels that require "fan knowledge."

"It's inevitable some proportion of that will happen, and very hard to prevent it completely," Gara explained about the eBay sales. "We did think things through. But in each and every case, the way you get hold of one of these consoles requires some fan knowledge, so we're trying to tap into the people who love the brand the most, and put them at an advantage, because they're the people who keep us in business, who inspire this whole 20 year legacy."

The 20th Anniversary PS4 consoles went on sale last weekend during PlayStation Experience and sold out almost immediately. For more on the commemorative console, which is modeled after the Original PlayStation and sells for $500, check out GameSpot's unboxing video above.
