The commissioner of the European Commission believes that a settlement could be reached in the Apple e-book antitrust case "in the coming couple of months." The European Commission is now market-testing an offer by Apple and four publishers in a bid to end the probe. The publishers involved mirror those from the US case over the same e-book price-fixing allegations -- Simon & Schuster, HarperCollins, Hachette Livra, and Macmillan are all named in the settlement offer. Publisher Penguin was also charged in the investigation, but is not participating in the settlement.
