Are there any issues with buying an X Play from a carrier? (XT1563 model)

I'd like to get one and my easiest way of acquiring one is through a local carrier, but I'm worried if it will have some kind of pitfall. Will I stop getting updates? Will they be slow to arrive? Can it be turned to a stock pure version without the bloatware via a stock rom? Is it worth it? Keep in mind it's the XT1563 latin american version. And the carrier is Nextel.
