just one reason: not a single "real" model shown. Only 3d and drawings, no more. Sounds lame to me. :S
That is a very good reason! It's also the reason I didn't participate in their former kickstarter, which ultimatly led to a lot of models I like...
Still roughly 24 hours to decide, and as long as the zeppelins and further Chaos Dwarves warmachines don't get unlocked I might stand the temptation
