We'd heard earlier that Google had "nothing to announce" in regard to Android compatibility with the newly-announced offline Maps support and 3D modeling, but look -- things change. We reached out to the company and urged 'em to dig a little deeper, only to have the following confirmed: "For offline Google Maps for Android, all devices with Android 2.2 (Froyo) and above will be supported." As for the 3D portion? "We'll have more details about device compatibility for 3D imagery on Google Earth for mobile at launch." After the event, we spotted a Googler using the 3D build on a Galaxy Nexus, so it's obvious that Android 4.0+ will be supported, but we have to assume that some of these older Froyo devices may simply lack the proper oomph needed to fly around the downtowns of [insert major metropolitan area here].
