EverQuest and EverQuest II Expansion Trademarks

The guys at Curse.com have noticed that Sony Online has trademarked the titles "EverQuest Underfoot" and "EverQuest II Sentinel's Fate", which are presumably the names of forthcoming expansion packs.
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.

So why would SOE do this? Well, they have the annual SOE Fanfaire coming up in a week, in which they'll no doubt continue their recent tradition of announcing expansions for their flagship MMO titles, so ensuring the trademark was in place prior to the announcement is always crucial.

EverQuest fans will no doubt recognize the Underfoot fairly quickly. It's an area that many wished would be introduced to the game early on in its lifetime; the realm of Brell Serilis, deity whom created the dwarves. Coming off its 10th anniversary and a new server ruleset, this would be the 16th expansion for the game.
