A report from AppleInsider points to a release of iTunes 7.5 as early as next week. The release will contain a host of small improvements and bug fixes according to the site, though no radical changes should be expected.
Better management of duplicate video and song entries will be included as well as a more stable experience for users upgrading their songs to iTunes Plus purchases.
Currently in late-beta, the site expects that the software could be released within the week, however notes that such high-impact releases such as iTunes can occasionally see unforeseen setbacks. Nonetheless, the release should be out by mid-November at the latest.
