We learned a lot about Google Glass this week. In doing so, we also learned a lot about Google.

It’s tempting to look at Google’s vast range of products and research projects and conclude that the company has more ideas than vision. (The difference is that ideas tend to be disconnected, whereas vision involves a coherent strategic direction.)

Where is Google going? Does Google even know?

A closer look suggests that Google is, in fact, an increasingly visionary company. And the fate of many Google projects is predictable.

Some are predestined to die eventually in the hellfire of “spring cleaning” (Orkut), many will live on forever as useful, profitable but not centrally strategic products (Gmail) and others form the strategic centerpiece of Google’s longterm future (Google+).

If we’ve learned anything from the truckload of Google Glass details this week, and from prior revelations that I’ll tell you about, Google Now is absolutely strategic and central to the future of Google.

More interestingly, Google Now’s cards metaphor looks likely to become one of the main interfaces for interacting with Google’s many cloud services.

Google will reportedly announce a new Nexus 7 in the coming months — possibly at Google I/O in May — and it’s expected to become a big seller. According to sources in the search giant’s supply chain, 8 million units are expected to ship by the end of 2013.

Thanks to those leaked screenshots that appeared on Tuesday, we’re pretty confident that Google Babel is no longer just a rumor, but a real product that’s patiently waiting to get its grand unveiling. And according to sources that are familiar with Google’s plans, it’s worth getting excited about.

They claim Babel aims to be “everything we have ever asked for in a unified messenger service,” with cross-platform syncing and a “first class iOS experience.”

Babel, a new chat service rumored to be on its way from Google, has been shown off in a bunch of leaked screenshots ahead of its official unveiling. The images reportedly come from a Google employee, and they show Babel running on a desktop. Not only do they confirm the service’s name, but also a number of its features.

YouTube Production Strategist Eileen Rivera teased Google’s Google Play 4.0 by posting a screenshot on Google+ on Sunday, ahead of the update’s official release. The image was removed shortly after it was published, but not before it had begun making its way around the web.
