Oil.Center was registered by a gentleman in Kuala Lumpur on 3/16/14 and is now on Sedo auctions with a day and a half left at 11,000 GBP. There is only one bid which looks like the owner received the bid and pushed it to auction on 3/24/14.
If its a legit bid, its kind of a ballsy move to send to auction, I personally would want to get that deal closed asap. I think if you have a legitimate buyer interested in something brand new like .center, you don’t want to allow time for buyer’s remorse to set in.
