IBM supports raw Eclipse

According to this article IBM will extend their support to the Eclipse Platform, meaning there will not only be support for IBM products based on Eclipse, but also for the core Platform functionality such as JDT or PDE. The support will be based on Eclipse version 3.2.

A nice outcome for the open source community is the new Eclipse section on developerWorks which provides tutorials and articles about Eclipse. That's where you will find for example Chris' 15 minutes GMF tutorial or my article on Cheat Sheets for Eclipse 3.2.
