I watched some scenes of the TNG episode "All Good Things...". As some of you may know, it was essentially a time-travel episode that had Picard jumping at different points in time in his lifeline. Now, in the "future", the Romulans were no longer a major power, as evident by the fact that there was no longer a "Neutral Zone". I doubt JJ Abrams and Bad Robot saw this as an excuse to destroy Romulus in ST2009, but would it be a coincidence that the fall of the Romulan Star Empire, as we know it, in "All Good Things" is because of the Hobus Star Disaster? It would certainly justify Starfleet's liberal usage of cloaking technology circa 2401 CE/early 25th century, and it would definitely tie into the plot within the Star Trek Online game that has the Klingons becoming antagonistic towards the Federation again.
Food for thought.
