The GWT PR machine has been offline for a year now. As it seems, the GWT engineers have been either working hard on a big and long project that is going to blow our socks off and hopefully they'll unveil it at Google IO 2012 or Google is winding down the project which would be a huge pity. The event that got me worried a lot is when their developer relation engineer David Chandler was moved to another group. David's blog: http://turbomanage.wordpress.com/
So far I have not heard of the name of his replacement.
Google should we worry or get excited?
