The news of the hour for geek movie fans is the sudden appearance of a plot synopsis for the third Spider-Man movie. You can read the full three paragraph summary here, but for now I'll break it down for you to hit the important bits. Mostly, it's a list of confirmations of previous rumors -- presuming, of course, this synopsis is legitimate.
Gwen Stacy, daughter of the new police chief, will in fact develop a crush on Peter, causing some sort of love triangle as Pete and MJ are finally getting their relationship off the ground.
Jameson will hire investigative journalist Eddie Brock to follow Peter around and figure out why MJ would leave Jameson's successful son for this loser kid.
Sandman will come into being as an escaped prisoner hiding out on a remote beach is caught in a dreadful accident and finds himself turned into a shape-shifting sand creature.
While investigating a crime scene Peter will find a "black substance" which merges with his costume to give him new powers. Hello, Venom.
Harry finally snaps and becomes the new Goblin, teaming up with Sandman to fight Spider-Man.
Lives of people "close to Peter" will be lost. This probably means MJ, since she isn't supposed to be alive currently anyway.
Eddie Brock will become "distraught" for some reason. At this point, the "black substance" departs from Peter and joins up with Eddie to form sequel fuel.
