Amazingly, the whole release schedule for 2013 showed up today. There are many exciting new things in store. I've taken the liberty of skimming the list and providing some conjectures as to what these releases may bring along with them.
Information coutesy of Apocalypse 40k. You can find their original article here. and my notes in orange.
Vivin on Warseer dug up this on theonering.net, a Lord of the Rings forum. It is the 2013 Games Workshop release schedule. Johnmclane then purged the hobbit stuff so we have just a 40K release schedule. And there are some impressive things here. The full list can be found here.

200462412010202 Space Marine Astartes Battle Fortress Tower / Pillar of Heroes PL 02 cc
200462512340209 Space Marine Astartes Battle Fortress Monastery PL
Wait... A FORTRESS? This is so Fisty it hurts! I can't wait to see how this works. Never thought I'd be this pumped for a terrain release.
208281612050205 Eldar Lamia Strike Fighter / Moon Siren Bomber PL
208283611550205 Eldar Jetbikes PL
208287930150207 Eldar Warlock with Force Staff RE
208288530950204 Eldar Swooping Hawks RE
Strike Fighter and Bomber, eh? Bout time they got some air support. Though I'm a bit bummed that it won't be prereleased as a WD update. Eldar could use a boost in the skies.
200470512040203 Space Marine Land Avenger PL

200469630140209 Space Marine Terminator First Hand RE
200469230140203 Space Marine Librarian with Jump Pack RE
Land Avenger. I wonder if that's the medium transport that the interwebs have been mumbling about lately. Skyshatter Cannon, perhaps an air equivalent to the Thunderfire Cannon? And I wonder what the Praetor Warmachine will be. Sounds like something between a Dreadnough and a Dreadknight... interesting.
200462811440204 Space Marine Neophytes PL
200464511440201 Space Marine Techmarine with Artificer Squad PL
200468011440204 Space Marine Sword Brethren / Nightflame Veteran Squad PL
200472230140203 Space Marine Librarian Epistolary RE
200475630110203 Paladin Marshall Sieghelm RE
New Black Templar! Yay. I wonder what an Artificer Squad is. New Marshall sounds cool, too.

200480130110202 Severus Agemman, Regent of Ultramar RE
200480630110207 Helveticus the Ancient, Bearer of Honour RE
Again, the Avenger. Looks like a Salamander variant and an Ultramarine variant. I wonder whose the original is. Iron Hands are getting some attention, and we even see Captain Severus (of the horrible Ultramarines movie) introduced as a model. Looks like a new Vanilla codex is on the way as well! With Bionics making a return and a new Defender upgrade... oh man. I can't WAIT for this codex! :D
201278911240205 Ork Warbuggy / Deff Racer PL

227162030941106 Dark Eldar Grotesque Squad RE
The last trickling of DE models?
202321411411107 Imperial Guard Storm Troopers / Iron Cloak Veterans PL
202342311811101 Imperial Guard Hydra PL
For serious? The Hydra is still a YEAR out? That is madness. Hopefully the Stormtroopers get some badass new sculpts. The generic ones need some tlc.

201279911440206 Ork Meganobz / Painboy Cyborks PL
201285130140209 Ork Warphead RE
Flying Fortress and Gun Fortress? Orks get more awesome every time. Temped to start them up with their new book :)

201284130740204 Ork Boar Squigs RE
201284430940212 Ork Squiggotaur RE

200467911540205 Space Marine Gale Claw Supremacy Fighter PL
200465011440203 Space Marine Space Marine Tactical Squad PL
200465512010202 Space Marine Land Raider Medusa PL
Yes! Scouts with rapid fire Grenade Launchers! Finally a load out that doesn't suck! A new Land Raider as well. Medusa means it's obviously for the Iron Hands, but hopefully they don't mind sharing with their battle brothers :) Supremacy fighter... guess that means it's time to kit out the Stormtalon for anti-ground work.
