I do think Stern has taken cost cutting too far, but I like Spike. It eliminates a mile of wiring, dozens of connectors, unneeded transformers, diodes everywhere, fluorescent tube light, etc. Simpler is better. Lighter is better too. Sure there will be some growing pains. When Sam came out Stern had to replace every single CPU board in the first game six months after production (WPT). We also remember the growing pains JJP had with their networked LED boards. That was a disaster way worse than any SPIKE problems.
Funny how people who don't really understand the SPIKE system are so fast pile on and bash it. Mob rules and bashing Stern is in style. Systems like SPIKE are inevitable progress, just like an LCD display and the DMD before it. Stern is using automotive technology and we all know how much more reliable cars are now than they were 20 years ago. They will get it right, because it will cost them money if they don't!
Yep the Pro playfield pegs suck, but on the other hand I prefer the video game style lock bar latches.
