It’s confirmed – Office 2010 will come in 32-bit, 64-bit flavors’
Microsoft has confirmed that Office 2010 will definitely be shipping in 32-bit and 64-bit versions. 
The 64-bit versions of Windows will no longer have to emulate a 32-bit environment in order to run Office 2010, provided that the user has the 64-bit version installed.
With 64-bit OS usage rapidly increasing, it’s good to see that the next version of Office, expected to arrive sometime next year, will come in both versions. For those wondering, Office 4.3 was the last 16-bit version and Office 95 was the first 32-bit version (to match Windows 95).
Screenshots of the alpha version of Office 2010 was leaked in January. Microsoft will ship Service Pack 2 for office 2007 this month before Office 2010 arrives.
