I missed this two weeks ago when it first appeared on Inside Office Online, but it appears the official name of the next version of Office has changed:
The next version of Office is officially known as the 2007 Microsoft Office system. Little ‘s’. Year before the product. Exactly 32 characters. Naturally, Office Online editors balked. When newspapers, trade journals, bloggers and even company executives are saying Office 2007, you assume that’s going to hold muster with branding. It’s not. When even SteveB himself gets flame mail (OK, maybe only a flicker mail, but still an e-mail) reminding him to use the proper wording, you know it’s serious.
I predict this will go exactly nowhere. Unless you’re a salmon, swimming upstream just wears you out, and this attempt to change the established convention for naming computer software is most certainly an upstream swim.
Windows 95, Office 95, Office 97, Windows 98, Windows 2000, Office 2000, Office 2003, Windows Server 2003.
And they want to break that string with 2007 Microsoft Office? It’ll never catch on.

At Bill Gates’ keynote address at WinHEC today, when it came time to announce the availability of the beta, he missed a beat as he paused to think of the correct phrasing — 2007 Microsoft Office system — and wore a silly grin when he got out correctly.
Not to mention the version number of any software is always listed after the the name/title of the product. Although I write dates as 23 May 2006, in the US, most everyone writes it as May 23, 2006. It won’t change, and it doesn’t have to. Same in sports, too. You can call it whatever corporate you want to — Petco Park, Verizon Field, MinuteMaid Dome, Coors Field, etc. But for Yankee Stadium, it will always be that and nothing else.
