For websites, it is Expression Web. Currently in Beta 1 and not part of
the Office family.
For Sharepoint sites, it is SharePoint Designer which is part of the
Office 2007 beta.
Now FrontPage is specific for web (Expression) and Server (SharePoint).
We waith for only one version in the future or new version of this specific
area software for web dev and desing.
These are two new products. Why would you wait for one product if MS
just split them?
Both products have a lot in common (they were split only several months
ago), but EW won't have the SP specific components while it will have
the web design specific things that SPD won't have.
Personally I think, the split is the best thing MS could do.
