I don't think the news has fizzled out, but it's something they're looking into. One of the primary questions being with which aircraft? That ties into the fleet review which they announced would be occurring into the end of '17.

JB ordered additional A321 aircraft this past year without specifying engine type/configuration. Once that decision is made, we'll probably have a better look into their thinking (at least in the short term). Should they choose the A321LR (NEO engines + other mods) that would be a clear indicator of longer range and potentially transoceanic flying. Of course other paths exist like sticking with shorter range A321NEOS and obtaining other long range aircraft (ie A330) or to not invest in any longer range aircraft other than the A321NEO currently on order.
