Beta releases have become a great way to discover potentialy unannounced products by snooping around in the files that accompany the beta. Ed Bott did said snooping and is now claiming that Office 14 will ship in 32-bit and 64-bit flavors.
Located within the Migwiz.xml file shows the code extensions that prove that a 64-bit version does exist.
This is great news for users that can take advantage of the 64-bit flavor and should come as welcomed news that Microsoft is expanding support for 64-bit. One day soon we will hopefully be able to drop 32-bit forever.
