Well, my movie blog's unsourced rumors say that both of those sites are full of shit, and that the real director of STIII is going to be Anthony C. Ferrante, director of the smash hit SyFy TV movie Sharknado. The film will be titled Star Trek Bearpocalypse (no colon) and the plot will revolve around the Enterprise saving Earth from a global blizzard full of genetically engineered polar bears that were created by a rogue Starfleet admiral, borrowing heavily from an unfilmed Damon Lindelof script for Lost. You heard it here first, folks.
Seriously though, it's way too early in the game to be getting worked up over completely unfounded rumors.
