Just to double-confirm - the classic rich-text editor (with the tabbed interface shown above) is sticking around for the time being. We will eventually retire the old rich-text editor, but there is no date set, and I do not anticipate it being any time soon.

As mentioned elsewhere in these comments, the way you use the source editor within the new VisualEditor is not set in stone - it may potentially end up with a similar kind of tabbed interface.
