While Microsoft has delayed the next version of Office, Danish CMS vendor Sitecore has recently announced that it will fulfill its promise of delivering the next release (V5.3 due out in July) based on Office 2007 usability principles. According to the company, Sitecore's updated editor is designed to "match the user interface of Microsoft products as closely as possible." With this bold announcement Sitecore demonstrates its impressive engineering skills, but as always licensees should make sure to look past the initial screens and test carefully, particularly since new UI concepts are being introduced here long before Microsoft has acclimated the marketplace to them. CMS Report readers already know that Sitecore is actually more web development platform than CMS.
