Well most of the new season has started now, I'm going to highlight the ones that have stuck out for me.
K and
Zetsuen noTempest I'm going to put in the
awesome stuff is happening but I have no idea what's going on category

Both look interesting yet hard to follow, worth picking up.
Tonari no Kaibutsu-kun AKA The Monster Seated Next To Me, in what looks to be a season of mostly romantic comedies this one is looking to be the funniest anime of the season. Even if you don't like romcoms that much I highly recommend giving this one a chance. Mini-spoiler; both characters have already confessed after the second episode, so none of that tearing your hair out waiting for two awkwardly shy kids to get to grips with their emotions
Psycho-Pass - Think of a cross between Judge Dredd and Minority Report only the guns the police use are the "judges", which are connected up to an anti-criminal super computer or something. The guns basically decide what level of "criminal" the perp is and as to what level of force to use (i.e. paralyze or lethal). The Minority Report analogy is because the guns can also tell if the perp is likely to become a criminal/commit a crime. Crime also seems to be somewhat "contagious", being a victim of crime is likely to raise your "criminal index" or whatever. The "psycho-pass" are a group of ex-cons specially hired/deployed by the police to deal with the worst kind of criminals. Looks to be a pretty interesting (and somewhat gory) anime, worth picking up.
JoJo's Bizarre Adventre - ZA WARUDO! Need I say more?
BTOOOM! - Looks to be the dark, gritty and somewhat gory anime of the season. Think of your average team based FPS/shooter but with bombs instead of guns, then make people do it for real and bingo. What's it with rape with these kinds of anime? Going to have a dark anime? Make sure there's a schoolgirl who gets raped or attempted rape just to show how dark the anime is...
Robotics:Notes - Light hearted slice of life anime about a robotics club at school that are making a giant robot, worth a watch.
