At the beginning of March the WLW team posted some screenshots of the next version of Windows Live Writer: New Version Of Windows Live Writer, with Screenshots
The new UI was like all the Windows Live tools, with a new window to add images and other changes to the core plugins.
And it also have the possibility to add tables.
Today I found a post on <edit>, that linked an exclusive image of a more recent screenshot of WLW.
As you can see they removed the Window Live look&feel, and reorganized a bit the menu and panels around the UI.
Looks like a promising next version: too bad I'd have to find something new when I'll move to the Mac OSX later in October
