A few games last night that I'm aware of:
Dark Elves and Vampire Counts VS Dwarves and Lizardmen
Orcs and Goblins VS Skaven
I was involved in the 2nd game with Jake, and my lord was it a bloodbath. Orcs wound up winning the day... barely. I think the first two turns had the Goblins lose about 60-70 models... then turn three had the same thing happen to the Skaven. The sort of game you love, lots of death and destruction!
For a total count, I think we started with about 300 models combined on the board... and wound up with under 30 left!
