I'm interested -- what're we betting?

That might all be right, but Zitt seems to be betting that not a single buyback of any JJP GnR will occur, when it sounds like JJP is already offering them to at least a few folks. To win the bet all I'd need is for one customer to accept a buyback (and for JJP to cut the check, of course). Those odds sound alright to me.

People keep saying this, seems unlikely to me that JJP is to the point of promising buy-backs without any intention of ever fulfilling them. That would seem like “end of days” type behavior for a company.

Have you asked for a refund? If you point out the extensive changes JJP has made to the warranty since last winter, coupled with the ongoing playfield issues which were covered by the "Bumper to Post" warranty at the time you preordered (assuming you put down your deposit under the old warranty) but now are not, you've got a pretty good argument that they've materially changed the deal and you're entitled to a refund if you want out. Under the circumstances, I would think a bit of foot-stamping should do the trick.

Just for reference, here's the "Bumper to Post" warranty pulled from the November 2020 GnR manual on JJP's website:
Old Warranty

And here's the more limited, Stern-style warranty from the current GnR manual, which based on the date appears to have gone into effect in March 2021:
New Warranty

A better question is why are we discussing the speed of JJP games in a playfield defect thread?

It's not too surprising that JJP would move from an "everything's covered" 90 day warranty to essentially copying Stern's warranty language. Following the market leader is usually a safe bet, and the limited written warranty doesn't seem to have hurt Stern's sales any. The surprise to me is that JJP apparently made the change mid-stream during GnR production, as opposed to just quietly slipping the new warranty language into the manual for whatever the next game is.

Regardless, given the wholesale revisions of the warranty language I'd think that anyone who preordered before the the language changed has a good argument for getting their down-payment back because they're not getting everything they bargained for when they cut the deposit check.

I admittedly participated in the off-topic GnR discussion from the Mandalorian thread that you ported over here (tip of the hat for the off-topic double-dip). That said, this thread isn't about GnR gameplay quality, it's about GnR playfield quality. Speed of play and flipper snappiness don't enter into it.

The TBL playfields are Mirco, but were produced more than 5 years ago. Mirco did a big equipment/process overhaul a few years back, and speculation is that caused the current adhesion and chipping issues. At some point DP will run out of old stock playfields and will have to decide if they'll use Mirco again going forward, hopefully he'll have worked this out by that point.

A pooling poll?
