As you can read on Winformant.com, Microsoft Corp. renamed the new Office 2003 software suite to Office 2003 Systems.

All known products such as Word, Frontpage etc.. will now be named 'Office 2003 Systems'. The changed name will be included in the upcoming Beta 2 of Office.
But the strange thing is, that when you buy the standalone version of Word or Excel, it will be named MS Word 2003. No 'Systems'.
We will see...
