I've decided to hold off a few weeks on the Tyranids. I had meant to go to the store to pick up a Hive Tyrant, but didn't have the time. Good thing, too!
GW is doing a new army for the new year thing and putting out a bunch of getting started bundles. They'll be selling a Hive Tyrant, 3 Warriors and 10 Gargoyles all in a box for $85. It should go up for preorder on Friday. With what I already have, that'll be a nice core to an army.
I'll post pics of what I intend to do this weekend once the preorders go live.
