This is old news. I've reported this over a year ago on the forums, regarding the 2TiB disk limit for Boot Camp. The thing is, essentially no one uses the forums for pre-sales research.
For the 2TiB limit to be broken, Apple needs Boot Camp to support EFI boot of Windows instead of the present CSM-BIOS boot. Further, the EFI boot support in Windows 7 is marginal, so I'd sooner expect Apple to support Windows 8 only for EFI booting, assuming they do it at all.
Further, the Fusion drive is a proprietary Apple solution based on Core Storage. Windows cannot use that. So any solution for natively booting Windows means using only a portion of the HDD.
So your best bet now is VM, and in fact Boot Camp isn't a particularly great solution for most Windows needs. For those who want to play games, they're better off with game specific hardware.
