Not sure if there has been any other discussion about this, but I'd seen that the X and G are slotted for an update to the next iteration of Android when that drops later this year. I spoke with a customer service rep at Moto today who implied (but didn't say outright) that we should expect Android L to make it to the Droid Maxx too. Here's the relevant excerpt from the conversation:
Joe: OK thanks - so are you saying that it [Android L] will become available later this year, but just hasn't been announced for release yet? I know that the final product is still underdevelopment and that Motorola has committed to updating the G and X, I was just wondering if a similar commitment to the Droid Maxx is out there
Joe: *under development (i.e. Google hasn't released it and published it to the AOSP yet)
Arrianne: We are always looking into improving our devices through Android Software updates, as of now we cannot provide an exact date yet, but for the improvement of the Droid Maxx an update will be sent you for sure.
Joe: Great, thanks for letting me know! Have a nice day
