I'm loving the new Tyranid models, apart from the goofy looking Winged Tyrant. I can see many a conversion to Epic Heirodules and Heirophants using the Tyrannofex kit.
The Space Wolves kits continue to ruin what was once a great army. I feel that it's actually a shame to see the dreadful concept of Thunderwolves getting models thus cementing them in future codexes.
Still it's nice to see the classic models of the range getting the Finecast update. May well pick up Bjorn now, since it won't be quite the pain to put together in resin as it was in metal.
