It's always interesting to see the flurry of Google releases in the month leading up to Google IO. My understanding is that projects hold out on releasing in the hopes of being included in the Google IO line-up, but release just prior to (or after) Google IO if they didn't end up making the cut. I don't mean to belittle these projects (this one looks quite good, for example!), just pointing out that you can potentially get a read of Google's current priorities by comparing the projects released surrounding Google IO versus the projects released at Google IO. There are some other factors to be mindful of, such as Google IO's focus on developers, however.
