Looks like they are stuck in time, with no upgrade path to the latest verson of Android, 4.0 (aka Ice Cream Sandwich). This just illustrates one of the big drawbacks of the Android market...
nice find, but it's hardly new news when it comes to Android... (AFAIR)Nexus and Droid owners have been pretty much left in the dark with major updates... I can't find it at the moment, but there is an article explaining just that even before Ice Cream Sandwich was released.
Another reason why I don't find Android devices to be for me.
