Since there is SO much speculation as to why people are buying Wonka and Dialed In 'suddenly', I can at least offer my personal reasons as a player/collector.
I have a buddy whose opinion on game I trust quite a bit. He likes games with great shots, some flow and depth of rules/modes. He has been talking both of these games up (and JJP games, in general) for quite a while. I get first 'dibs' on his games when he is done with them, and two weeks ago he mentioned that his Wonka and Dialed In were never leaving his collection. That got my attention, so I started looking around, and I decided to go NIB from JJP (they had a few Wonka CEs left), even though I have been avoiding newer games due to play field issues. We LOVE the game. My wife and step-son have been playing, and even my step-daughter and her boyfriend have shown interest. LOVE it.
Well, after JJP quickly sold out of Wonka CEs, and I started to read about a run on the title in general, I felt like I got in just in time. SO...that got me thinking about securing a Dialed In...again, a game I was ALWAYS going to get, at some point, but loving my Wonka CE so much and seeing what was going on, I happened to find a DI CE NIB yesterday, and then came on Pinside to see people talking about a possible run on THOSE. So, do I count as a "I just have such deep pockets, and I HAD to have them just because of FOMO even though I don't care bout the titles", or did I start to see the writing on the wall as far as both of these titles I wanted because of reputation becoming harder to find NIB, so I pulled the trigger? It is the latter.
Yes, I paid NIB CE prices for both, but since I expect them to both be in my collection for a LONG time, I am very happy. So, I don't know what other peoples' stories are, but that was the reason for 2 JJP NIB sales this past two weeks.
