Multiple sources are now reporting that the new Tyranid codex ran afoul of some manner of printing error which will push the release date back about a week to mid January.
Broodlords are said to be a squad upgrade for Genestealers to allow the unit to count as troops, rather than the expected HQ selection.
The Trygon is said to be $49.50 USD and will allow construction of 2 (some say 3) different models (the Trygon and Mawloc)
The new Tyranid Battleforce is said to contains no new models, with the Carnifex being swapped for warriors and rippers.
Gaunts are reported as being split up into seperate boxes of Termagaunts and Hormagants (a dozen for @$24 USD), so if anyone wants to buy the current mixed box of gaunts, grab em while you can.
UPDATE: from Sildani in the Comments (THANKS!)
