Quoted from cpsystem3:New post on Stern's Facebook -
The team at Stern are constantly working on improving and making sure our games are the best they can be. There are code updates being worked on for our past few titles. We have no estimated date for when they will be complete.
I don't know if any of the Metallica guys are on Twitter, forums or whatever, but I wonder what their reactions would be if they knew that their names were on incomplete (and in many cases broken) product and there was almost no communication with their fans.
If Kirk Hammett was selling a guitar with his name on it and there was warping in the neck on some, bad soldering on others, or some other issue, and six months on the manufacturer was still vague about a resolution, it feels like there would be more movement. Is it because the pinball machine is niche and not in the band's line of sight?
Seriously, if pressure coming from customers who spent $4-8k isn't enough to move Stern, maybe pressure from license holders would be.
