Looks like they changed their mind about calling it Planetside Next. The countdown seems to be for an announcement set to be delivered at Fan Faire 2011 in a couple of days, 7/7 at 7 PM PDT. Also, from the site metatag:
PlanetSide 2 is the only first person shooter that delivers truly epic, massive combat on a scale never before seen in stunning, breathtaking detail. Be a part of explosive action in a futuristic world with forces ranging from tactical squads to thousand player armies all taking place in real-time on enormous open-world continents.
