If you ride groomers only, just find a big cambered board you like. Most people are selling them used cheap on craigslist. WInterstick makes a great board, the Tom Burt Model. Last years Burotn Supermodel was fun.
You will not like the new rocker options because they are all half baked and still evolving. C2, or Never Summer's version or the Burton FLying V comes damn close to feeling like camber, with less "catch" but less catch means less effective edge, AND that means on the Ice coast, less grip. All the different sidecuts and Magnatraction do not compare to effective edge, don't let anyone fool you.
Check out the Capita NAS, or a Custom X, Arbor Aframe is cambered?
