Xtext is a sub-project under modeling.tmf. It's a language development framework, which is used to implement all kinds of languages and corresponding IDE support : http://www.eclipse.org/Xtext
Xtend is *one* language we developed based on Xtext. We did it as an example under Xtext so far, but it's no longer just an example, so it doesn't fit into the scope of Xtext anymore.
Code-wise we'll have to move a couple of bundles from Xtext to the new project, but the majority of the code base stays in Xtext and it will still be very active.
Also all the existing Xtext committers will stay and the people I listed in the document should become committers on tools.xtend.
Regards,
Sven
