Oh that would be a sad day for small design shops around.
From the Cuban Council blog:
We’re very excited to share that some folks on our team will be joining Google to focus on design aspects of Google+. Having worked closely with a variety of Google product teams since 2005, we’re thrilled to have the opportunity to focus our creative efforts within the organization.
Techcrunch makes it sound like a acq-hire, which would be horrible as the Cuban Council brand is certainly stronger than the Google+ brand. CC has been around longer than all of Google and they were responsible for the original Designers Lunchbox: Kaliber10000 after all.
