I think with the Elite's that's just the way the Helmet looks. If you look at the new MCFarlane figures the Grunts and Jackals with the bigger/different looking heads are actually called Storm Grunts and Storm Jackals, so I'm guessing there's a story reason for them looking this way if they even have a specific name. There's nothing called a Storm Elite however, and the figures look the same as the old Elites, his helmet just makes his head look bigger. In the U.S. at least, you can find the figures at most Targets right now in a big preview figure 4-pack. There's a Storm Grunt in there and I believe I saw the Storm Jackal on the back of the packaging as coming soon or something.
