There are some very strong rumblings that starting with Series 9 there will be pack-in figures of large scale that will be included with each figure of a Wave. The two being mentioned are Galactus and a Sentinel
Case packouts would be equal and you would get a piece of the larger figure in each package to assemble a large (16") figure. Seems like a cool idea and a great way to get Galactus and the Sentinel
Also Series 8 may be out before Christmas, I'm getting them all except Man Thing, Black Widow Variant and maybe the Storm Variant.
