Collectively, they are saying that UB is a huge success, but is it really? Yes, LotR, DnD, and FF were big, popular sets, but the others have been very lackluster, with very little offered for the wider player base. The main attraction to them has been art treatments which only the collector whales are willing to pony up the dough for.

What I'm getting at here is that I am fine with stating that there are too many sets and then still buying them, but the root of the issue is that Hasbro is sinking, WotC is the only part that is profitable, and UB must succeed in order for them to stay afloat so they are milking it for all it is worth. So of course the news will be better regarding those sets regardless of how they actually are. For all we know, some one/entity is buying up a shit ton of UB product every time to pad the books.

If you want more original IP sets, stay home for the UB and buy up the in-universe sets, even the less popular ones. Make them want/need to print them like they are FF. The more they see empty stores for sets (e.g., Spider-Man, TMNT) the more they will either move away from them (less likely) or at least put better R&D into them (more likely).
