RUMORS: 40K - WFB 2013 Schedule
Posted by Larry Vela
The most interesting things show up in the dead of the night. Here's the latest notes from the singing holiday birds on what 2013 has in store for Warhammer 40,000 and Fantasy...
JAN: Dark Angels
MAR: Wave month (hobbit, warriors of chaos, 40k)
APR: High Elves
JUN: Summer wave (40k, supplement book for 40k)
AUG: Mystery Box
SEP: Wave month
Now, as usual, these things tend to get more speculative as you go outwards in time, but overall these line up with what we've been hearing from a variety of chatter. We've been hearing for a while that the "Mystery Box" is a fully revamped Blood Bowl. This list would certainly be a "year of xenos" - I can hardly wait.
UPDATE (16 Dec 2012):
Flyer Waves Coming: Dark Eldar, Eldar, Tau, and Tyranid
Just to be clear, this came out when I was in the middle of my move, so it was missed on my end. I wanted to make sure that people did not miss it, because it has some very interesting rumor bits, including the Ork Wave, a certain Dark Eldar flyer I have been wanting, and mention of tyranids (please I want to see them on the tabletop again).
These came out on the 9th, but hey its the weekend, and its catch up time. Please do not forget that these are rumors.

Here's the latest out there on the grapevine regarding both Warhammer Fantasy and Warhammer 40,000 in the months ahead.
via the little birdies:
Late-December-January: Dark Angels
February-March: Chaos Daemons (still LOTS of chatter of a synchronized release of 40k/WFB Daemons books like Games Workshop did last time)
March: 40K Miniatures Wave ALPHA (see below)
Another Hobbit release wave is in this quarter as well.
April: Warhammer Fantasy Armybook
May: Tau Empire
June: 40K Miniatures Wave BETA (see below)
40K Miniatures waves are said to be:
Ork wave: with buggy, wartrack, updated Battlewagon, coptas, flashgitz, and tankbustas
Flyer wave: with: Eldar, Tau, Tyranid, Dark Eldar kits
The order of those two waves is in contention, but both keep coming up in chatter.
WFB Army books for 2013 are said to be "pointy ears and 8-pointed star" variety.
Apocalypse Supplement in the Works
There are rumors of a 40k supplement coming next summer, and I have heard several different vague hints on what it might be. This evenings rumor bit is a brief, but says that an Apocalypse expansion is being worked on, to update it and bring it into line with 6th edition.
Could this be next summers expansion? A White Dwarf update?

i heard something that we could be looking at a new Apoc rulebook soon too bring apoc games in line with 6th edition, could be interesting and im getting excited.
And here is a modified schedule to include some of these specifics:
Jan: Dark Angels (release will be a week late due to the holiday season according to older rumours) Confirmed. Tangentially, the late US release of the WD was true as well (even digitially)
Feb: Daemons (Fantasy and 40K according to rumours) Warriors of Chaos instead. Looks like Daemons go on pre-order at the end of Feb though with current rumours though, but this throws a wrench into the current schedule as it stands.
Mar: Ork or Flyer Wave (this could go either way at the moment), also Hobbit and Warriors of Chaos waves
Apr: High Elves
May: Tau (for real this time as the source isn't Ghost21)
Jun: Ork or Flyer Wave (this could go either way at the moment), supplement book for 40k (likely a new mainstream Apoc book), Also Annual Price Increase Month
Jul: Lizardmen (with both these and High Elves on the list this year, and Vampire Counts and Tomb Kings not to long ago it seems GW is trying to reign in the "Lolz, Magic" side of the game by updating the armies)
Aug: Mystery Box (Rumoured to be Blood Bowl, I almost want to call shenanigans and predict another new game that will only be around for a short time, ala Dreadfleet).
Sep: Wave Releases (No ideas on this. Just for fun I'll call Finecast since we haven't had one in a while and there are still a number of models to go that need to get switched over)
Oct: ??? (no rumours yet. Just for fun, I'm going to say that this is probably the SOONEST the Sisters will see an update. No source, no logic, just conjecture because I feel like putting them in the blank spot for now).
Nov: Eldar (aka, High Elves in Space).
Dec: ??? (not typically a release month. Perhaps more Hobbit stuff to fill the gap).
