Chris, this IS a whole new design. Yes, it's still based on the diamond, but the diamond still works. The new core design says it's a combination Asymmetric and Symmetrical. It looks like it'll give you the best of both worlds.
If you want some silly stupid shape that looks completely different, but doesn't work all that good, then go ahead and waste your money.
But, if you want stuff that works, I'm sticking with Lane #1's diamond core. =:^D
