Quoted from Nokoro:

This whole discussion reminds me of when I was a kid and bought The Legend of Zelda cartridge for the NES. It was somewhat revolutionary at the time because it used a battery to save your progress instead of a password like other games (e.g., Metroid). I remember when I learned that the battery only had a 5 year life that I expressed frustration to my father. He laughed at me and said that I wouldn't be playing in 5 years anyway. Sure enough, after a few months, I had conquered both the main and secondary quests multiple times and moved on to other games. Later in life, I was able to download the original The Legend of Zelda and play again. People's feelings change, and technology has a way of making things happen.
Right now, I say WOZ will never leave my collection, but I have no idea how I'll feel in 5 years. At some point, all versions of the boards will stop working and replacements will be needed. Someone will offer something. I was more concerned with the USB dongle that has an encrypted code that you need to run the software. I remember asking about it in another thread and wondering how the pin would function if that dongle stopped working and JJP was out of business. I believe Lloyd responded and said something like, "the pinball community is full of creative people." There are a ton of WOZs out there owned by home collectors that will be kept in pristine condition. It is one of the greatest machines. There will be demand for it in the future, and somehow, people will find a way to have replacement parts.

Quoted from 27dnast:

Exactly. This goes without saying that JJP still has lots of replacement boards and maintains the capacity to repair boards that are no longer working.
This whole notion that JJP is lying isn't worth anyone's concern... worry about if it happens. Why sit around saying the sky is falling when it's not. There is zero proof not to believe JJP.
I strongly urge any one reading this thread with concerns to call up Jack and talk to him. Don't sit on this forum drawing conclusions from someone claiming to have a crystal ball. It's not worth your time.

Quoted from merccat:

I think a lot of the concern is simply a natural part of a technology transition. We have moved from universally available bulbs available anywhere by a number of manufacturers to a specific proprietary board with (currently) a single source. Not that its a bad thing as there are lots of fantastic benifits gained from going this route.
Warranted or not, thats going to make some people uncomfortable as they see shifts in the design of those propetary boards.
It also goes to show how much people love and care about their WOZ's that they are looking forward to something that *might* break 10-20 years from now.
Edit:
Full Disclaimer: I'm in no way worried about the current or future state of my WOZ... i just think its an interesting convergence between tech trends and pinball.

Quoted from KingPinGames:

hope the op got that answers he was looking for and is enjoying his machine!

Quoted from lordloss:

You were wrong about that 5 year battery life. A lot of original nes games still hold their save 30 years later.
