Don’t think the new year will slow down GW a bit. The Tyranids Hive fleets will return with a campaign and an surprising opponent.
via a source who spoke to BoLS on condition of anonymity
The Tyranids release window begins in January 2016
This will be a Tau-style release with the following
3+ new units
Several older resin models will be consolidated into a multi-unit build plastic kit
1 new plastic Gargantuan Creature
The Tyranid release window will include a Kauyon-style campaign book that details the Hive fleet’s struggle against their opponent.
The campaign foe is Astra Militarum
Astra Militarum will be the followup 40K release window.
~I’ll let you start to speculate on exactly what the Tyranid “decurion” rules and what thier Lord of War model may be.
