Prepare your party gear and break out the keg, people: Google is officially starting the push of Gingerbread to AOSP (Android Open Source Project) as we speak. Jean-Baptiste Queru just announced that fact, saying he was going to begin pushing the code to the AOSP, and the process is expected to take a few hours.
What does that mean for you? ROMs built on AOSP code (such as CyanogenMod) will now have access to Gingerbread, so expect CyanogenMod for Gingerbread (CM7?) to start cooking shortly. Since the code is now finalized, it also means that Google will likely start pushing out the Gingerbread update to the Nexus One.
