Personal educated guesses (since only Brunswick will know):
The Alien core shape was used the first time (As far as I know) in the Control Zone and has seen re-entries in overseas releases like the Red Alert Plus (
http://www.123bowl.com/ball.asp?ballid=2650) or Master Zone.
The Cheetah uses the core from the Monster ScreamR
The Shark and the Vipers use the Inferno core or its derivates with differeing RG and diff. values - at least they did until recently, before changing the pics on their website and launching the Chameleon recently. I am sure there was a 3D picture of the Inferno core, and the specs indicate this, too.
I guess there is still the Inferno core inside, despite the wacky illustration. I doubt that this is an all new core design just for Elite, and that they'd have changed it while the ball is still in production without further notice?
The R47 is IMHO a 100% original Danger Zone remake (same core, symmetric - see the specs), just with 2 colors in the solid PK18 shell.
