Until they add Java support they shouldn't even be using the Eclipse name.
I know Eclipse supports other languages, but essentially Eclipse is the biggest Java IDE so announcing this web editor but avoiding Java support feels like they just picked the most easy thing to show off.
Syntax highlighting is easy. What I want is a Java editor with code completion, code folding and error highlighting/error stripe. Otherwise we might just use Emacs over NaCl.
It seems that you're forgetting that Eclipse is not an IDE. It's a foundation. A foundation, similar in some ways to Apache, that owns many different projects. One of them is the Eclipse IDE. The other is Orion. Now tell me, why shouldn't a foundation named "Eclipse" be using the word "Eclipse" in one of it's own projects?
Edit: To be perfectly fair, Eclipse foundation is itself guilty for this confusion, because if you go to the "downloads" page on their site, you only see downloads for Eclipse IDE. You need to go to the "projects" page to see or download any other project.
It's not about showing off, it's about releasing early and getting some users to start a feedback cycle. To berate them over using the eclipse name because it's not what "you" want is just petty.
The idea of a web IDE is still a new concept. And maybe some things aren't meant for the cloud. It's awesome that these guys are experimenting with the notion. How can you expect them to just release a finished (open source) product out of the blue?
Java syntax highlighting is also supported. However, we have not implemented any outlining or content assist. Since we are building an integrated web-based toolset, we felt it important to target first the web client languages such as JavaScript, CSS, and HTML, so we can attract members of the JS community to Eclipse. Since we are self hosting Orion development in Orion, we need the JS features first.
