Gonna be longer than that--portable tools have the motors built in, they're not off-the-shelf parts, they're custom designs unique to the tool. So to bring in the corded version they need to redesign it with a 110v motor, order tooling, order parts, and get the line going--that's likely to be a year or more _after_ they make the decision, and they're likely to want several years of sales records on the cordless before they do that.
