I think it looks like a good game. I could see myself getting a premium at some point. I do wish the lock on the upper playfield acted as a ramp as well and that shot had flow to it.
I was a little underwhelmed with the stream...hard to put my finger on why...but I walked away thinking great art, great music (too repetitive, but hopefully they will fix that) cool light show, black knight toy is cool, shots and layout are ok and the upper playfield is ok)
I don't want to start a JJP vs Stern thing...I love both companies and my collection reflects that, but the hype of Wonka took my by surprise and has me really intrigued. I haven't been following that at all, but as I was watching the Black Knight stream I was thinking about their reactions to Wonka and comparing my reactions to the Black Knight.
Anyway, to sum up I think the Black Knight will be a good/fun pin and owners will be happy with it...but so far it doesn't blow me away.
