I doubt it. Based on the number of sessions at Google IO this year for GWT (many) and the number of sessions for Closure (one?), I would say they were outwardly pushing GWT much more than Closure.
I wish they would come out with more JavaScript tools. I have used GWT for a couple side projects, and while the tools and library are amazing, writing an app the "GWT Way" (using all the design patterns) is cumbersome and difficult, especially for a one-man-show.
Closure is better in this regard (mostly by virtue of being a JavaScript library instead of a Java library, IMO), but it's still overkill for quick side projects where something like underscore.js would suffice.
Why would they use Closure instead of GWT? Closure is just JavaScript. No waiting for the GWT team to build the features you need, no having to build those features yourself. And in my experience, when I need cutting edge with GWT, I end up writing a bunch of wrappers for JavaScript functions, which makes me wonder why I'm not writing everything in JavaScript. (Like I said, the GWT library is very compelling and when planning a large project, Java often feels more comfortable for some.)
So no, I doubt they are killing GWT, but it would sure be nice to see them develop some comparable JavaScript tooling (as one of their main points for choosing Java as the language of GWT is because of the quality of the existing Java tools).
