Looks like quite a few Jurassic World sets are on the way out. The Jurassic Park sets (76958, 765959, 76960, & 76961) are already gone from the targets in my local stores. My walmarts are also low on stock, so it doesn't look like there will be much good buy-in discounts for many of those as they sail into retirement.
The Giganotosaurus set is probably the best one to invest in. If they dont remake those two dinos, it could see a good spike like the Indoraptor, and Indominous Rex sets.
