Motorola device owners have been pretty vocal about their want for Android 4.0 Ice Cream Sandwich on their devices. Motorola in response to that, has kept an ICS rollout schedule updated and recently they made some changes to it that will either excite you or upset you, depending on which device you own.
Droid RAZR, Droid RAZR MAXX and XOOM 3G/4G owners have the most to be excited about as ICS updates for those devices should be rolling out at just about any moment right now. Atrix, Atrix 2, Droid Bionic, Droid 4 and XYBOARD owners will be waiting until the next quarter for their updates.
Own a Droid 3 or Droid X2 though? Looks as though you better start looking towards some ICS compatible ROM's as those devicse will be stuck on Android 2.3 Gingerbread for the remainder of their lifecycle, minus some bug fix and maintenance releases.
