Has Microsoft forgotten to file a trademark application for the name of its new operating system?

Microsoft has announced that the name of its new operating system coming out next year will be called “Vista.” As of the date of this posting, a search of the records of the United States Patent and Trademark Office reveals no applications on file for the mark VISTA owned by Microsoft. Is this an oversight or merely a consequence of the several day backlog for getting information about new applications online? Perhaps it’s just a load date issue.
