Let me clear some things up...
We're doing per average 8 to 10 games per week. We're hiring to increase that, but then we begin to out run some of our vendors, who are also working to increase their capacity. It's not an easy thing to manage to say the least. We aren't Stern or JJP and we're never going to be... we like where we're at. 
The latest batch of butter cabinets is assembled and in production now. We do them all at once because damn you have to be careful and it's also a lot more work to produce the actual cabinets.
We've built over 120 now... the intent is to build as many TnA's as possible BEFORE Alice Cooper hits production in late May / Early June (best estimate).
We set a goal of building 300 Rob Zombie games in 18 months and publicly announced that... we did it in 16 months, AND had Domino's on the line at the same time. There will be some overlap of TnA and Alice. Nightmare Castle is a contract licensed game and timelines have to be honored.
It's not perfect folks, but we're doing everything we can here to reduce wait times for everyone.
