French rumours, relayed courtesy of HorticulusDK on Dakka:
(Since the Heachi / Temouloun case I won't name the - really reliable - source, but I'm sure you lot can easily find it) :
- End of spring : Drukhari codex (mid April) ; Harlequin codex (May) ; Kill Team (May-June).
- Summer : Imperial Knight codex (start August), Codex Space Wolves (end August), Gorkamorka (!!!) boxed game (September) - It will apparently be like the old game with new models (see the Orkish wheel Rumor Engine).
- November, December : Slaanesh (Daemons, maybe more Fulgrim ?), Orks Codex
Now these sound far more realistic to me than the set of rumours laid out in this thread. If true, Gorkamorka is a bit of a surprise though, albeit a welcome one.
Odd that it omits some of the things we either know or can very confidently predict to be coming, I.e. Deathwatch, Genestealer Cults and the three remaining Necromunda gangs. Obviously also missing SoB, SoS, Inq, Assassins, Legion of the Damned and Ynarri, but those could remain in Index purgatory awaiting either a fully fleshed-out Codex/new models or oblivion, whereas DW and GSC are fresh enough not to be at risk of squatting and not in desperate need of more models.
