This Stormtrooper is going to be everywhere eventually. And probably for less money. Packaging? It's just more cardboard to deal with.
And ultimately, that's going to bring the eBay price for this version down. People who just want the figure will grab the regular edition and demand for the exclusive will go down.
Not to mention that the 2015 SDCC packaged version will be sold at a convention in Germany in September, so that will put more of them into circulation after the big 9/4 glut.
