Unfortunately, like Paizo, I think they’ve come to understand that when it comes to what the general public thinks of as “D&D-esque” TTRPGs, there really is a 900lb gorilla in the room nowadays and it’s D&D. The sales of a 5E version of LotR, especially with the Amazon show coming out, will likely be a lot higher than The One Ring. Lots of 5E groups just won’t try new systems.
(And yes, I understand how ironic the above is when we’re talking about Lord of the Rings.)
Frankly, I’ll probably get it. They really killed my enthusiasm with the custom dice, then screwed me with misprinted official dice.
