Few things there. First, over time we will be allowing apps not allowed on the play store. That includes apps that can modify your system, adult apps, and so forth. Second, for apps like Hangouts and Facebook and even YouTube, we will be uploaded early releases. Often times there are new versions of apps on the way out but Google releases them in staged rollouts that can take days or weeks. With Labs, you can get the update right away. Great example from the past would be Hangouts 4.0, with its redesign, which a lucky few got very quickly and the rest of us were left waiting. With Labs we will get the APK and push it down to your device very quickly.
