Sony Online Entertainment - New EQ/EQ2 Expansions?

An anonymous reader wrote in to say SOE has apparently filed for two new trademarks, possibly indicating new EQ and EQ2 expansions that might be revealed at the upcoming Faire.  Since the tipster didn't provide a link, Google comes up with this from a site called Curse:

Through a bit of internet sleuthing we've discovered that recently, Sony Online Entertainment decided to trademark two new titles, one each for EverQuest and EverQuest II. The trademarks in question took place on June 10th, 2009 and are EverQuest Underfoot, and EverQuest II Sentinel's Fate. While nothing is announced yet, there's a good chance these two titles are the names of each game's respective expansions.
