If you click on through you can see Guy's blog post that this article is based on: https://blogs.oracle.com/projectfortress/entry/fortress_wrap...

He seems to imply that he'll be moving on to some other project at Oracle, but it's not really stated explicitly.

Presumably, he'll continue to head the Oracle Labs Programming Language Research Group (which most likely is doing more than just researching Fortress).

Although maybe the decision will be related to him going somewhere else (I'd imagine there's a lot of places that would fall all over themselves to hire Steele).

I hope he moves on to a better company. :) The guy is legend. It's hard to find much good to say about Oracle these days.
