From my understanding, Motorola will support the phone still and provide updates at least until it's 2 years old. Shouldn't be any different from any other version of Moto X. As far as availability on the '13 model, looks like you can only buy it off contract at online retails like Amazon and the likes for Sprint. I know VZW has stopped selling it in stores and online as well. It appears the '13 model got discontinued. Either way, I love my OG X and I'm having a hard time deciding to get the new one or not.
