If I am reading things correctly, Microsoft Office 2004 for the MAC just came out this spring.

"Usually" there is at least a 2 year cycle for new versions of Office. And the MAC versions are often farther apart than that.

As with any "new" version of Office, the biggest issue you will face is sharing your files with users who have older versions of Office.
When you know a file will be shared, make sure that you save it as an older version file.
