I've just clarified above. The current wikimarkup editor will be in place as before, the changes are to the layout, not to the editor. If you have RTE disabled, or switch to source mode, the editor is the same code and functionality as before.

Licensing and other important pieces will still be in place - I can't give exact details because we are telling you about this early, and not all parts are decided or coded. But we know licensing is important, and won't miss that out.
