iSlate could be the name, or it could be as obvious as "iPad Pro." It makes a lot of sense to also provide the more advanced device that takes advantage of Mac OS X. Apple is the king of incremental upgrades; some people just have to have it all (me included), and Apple capitalizes off of us that aren't typical users/buyers.
Also, I have to believe that the rumors of two different sizes, and two different OS's were correct. We even heard rumors of an iPhone based OS and a Mac OS X based OS. This really makes sense to me. The "pro" experience will provide everything the consumer version lacks... Camera, upgradeable RAM, FLASH support, Mac OS X application capabilities as well as App Store app Support, upgradeable SSDs, Artistic Digital Drawing, real graphics card, and OS X itself - ALONG WITH EVERYTHING ELSE THE iPAD LACKS. Really, Apple can take this a lot further than just its simple $499 iPad. I definitely believe that sooner or later, an advanced OS X iPad Pro version is coming.
