this happens with every toy line near its end. big example is toybiz. as the hasbro deal was coming in, the later ML and other toyline waves became much harder. Mojo and Modok waves were only available in toysrus's, while the final fantastic four wave from that toyline barley touched the market, leading to the collectable juggernauts of Dragonman and Kang the Conquerer.
This also happened to Indiana Jones. Remember Short Round's wave? Never saw retail outside of clearance stores and the internet.
happened to Star Wars's Comic packs. though those never made it to store. those became internet exclusives.
bucky ohair, the mario bros movie toyline, teenage mutant ninja turtles, transformers animated, the list goes on and on.
