Microsoft has announced plans to support new file formats for Office with Service Pack 2, including Open Document Format (ODF), Portable Document Format (PDF), and XML Paper Specification (XPS). In the past, Microsoft has created add-ons for users to be able to convert these files. But with these formats becoming more popular, it has gone one step further to build support directly into Office. With this announcement, the European Commission said that it will investigate the affect the move will have on consumer choice. “The Commission will investigate whether the announced support of Open Document Format in Office leads to better interoperability and allows consumers to process and exchange their documents with the software product of their choice,” the commission said in a statement reported by Dow Jones. Office 2007 Service Pack 2 is not expected until sometime in the first half of next year.
