Quoted from Williampinball:I still think the new MM will be made not as good as the older ones thats for sure ,it's like anything else out there ,they would lose money that way and I don't think they will ,but we will see how good they really are
To use your own car analogy, a new mustang is faster, handles better, is more reliable, is safer, and is more fuel efficient than a '65 Mustang. The old ones have nostalgia value, but the technology has improved tremendously.
There's no reason to think that the new ones will be inferior in any tangible way.
