data - What is the wire format for Google's new vector map tiles?


Google recently released new vector cartography for their mobile maps. I'm curious if anyone here has any insight into the wire format they use for transmission? I've experimented with a few formats over the years, including bencode, bson, variants of WKT and WKB, and gzipped, limited-precision geojson which I've found to be the best trade-off in comprehensibility and file size. I'd love to know what Google decided on, but I don't have an Android device to test with.
