This looks awesome!

 Quote from Snorri: Just got an email through from games workshop and Skaven are set for a November release.
Email promises lots of new Plastic and metal models and I really cant wait. Feel like all my christmases have come at once. Space wolves October Skaven November.

So apparently we are going to be seeing Tyranids coming in 2010... as well as the skaven. The rumours were brought to the gaming community by Warpshadow's: Terrorfex

News of the new Tyranids is running around the mill now:

The sources say they spoke to Phil Kelly during GD Germany.

-4 New Tyranid species never before seen in a codex, one of which will make the current carnifex "look like a dwarf".

-Tyranid Characters return... No so much individual creatures like Old One Eye, but these will be indicitive of big creatures that have survived through battlefields and evolved into something better.

-Plastic Hive Tyrant kit with wings.

-Codex is in the can and is written by Robin Cruddace (of codex Imperial Guard).

-Tyranids will have evolved rules and abilities to better counter the rapid emergence of mech that has accompanied 5th edition. (implied that Biovores will be viable)!

-Release in 2010
