From Office Web to Office 14 now, and I found Mary-Jo’s post useful as a quick update on progress. Office 14 is the next version of Office (the desktop based one), and in terms of version numbers I think they skipped 13 due to it being an unlucky number (or some such).
The post is a good summary, but also includes a few new items, such as the rumour that SharePoint 14 will include offline access (provided by the Groove technology). There’s also other speculation such as SharePoint supporting SQL tables as SharePoint lists and SharePoint as an archive for Exchange.
And perhaps even a 2009 timeframe (although unlikely).
