It will be interesting to see who's got the tool. Hopefully not someone who wants it for the "collection/cool" factor.
One thing i did notice is that the buyer is new to eBay and has 0 feedback, which isnt a bad thing, if they pay, but that also means, no one knows who it is.... until they say, or dont rather.
While it's possible, i really doubt it, it's more Sony's style to chase up where the tool came from. And probably ask eBay to remove it (even though it's legal, eBay would definately remove it, and give some bs lie about some made up policy, happens all the time. Ebay also have the right to remove the listing as a violation at the manufacturer's/companies request, no idea why.
So i think, if Sony were much bothered, they would have not let the bidding happen.
