Actually, Verizon released the Razr in November of 2011 and the Razr Maxx in January 2012 in the US, so we're still a little inside of that two year window. And if memory serves me right, the OG Droid got an update well past the 2-year time frame. IMHO, Motorola has been one of the best manufacturers (outside of the Nexus line of course) at rolling out OS updates. Maybe 4.3 or 5.0? JB 4.1 rollout was in March 2013, so I wouldn't rule another upgrade out.
