So when Jon Morse, in the article, says, "WISE scanned the entire sky for these and other objects..."

And then Michael Cushing, in the same article, says, "It's thrilling to me to know we've got neighbors out there yet to be discovered. With WISE, we may even find a brown dwarf closer to us than our closest known star."

Does this indicate that data from the entire sky is stored somewhere but not yet analyzed?
If that's the case, how much remains to be analyzed? Would they already have a good idea where to look for "nibiru" from observation of anomalous gravitational perturbations?

Or does it mean that only the "entire" sky from one vantage point was scanned?
If that's the case, how long would it take to do another scan in "nibiru's supposed direction? Would there be enough time to find and confirm it or rule it out before it does what it's supposed to do?
