I'd assume so however VMware typically does not discuss unannounced features, time lines, etc. per their company policy. So I guess it's a wait and see when although a partial quote from What's New in the VMware Workstation Technology Preview 2013.
New Converter - This Workstation Technology Preview includes a preview of the next version of VMware Converter. The Converter enables users to make Physical machines virtual. This version of the Converter includes support the following enhancements:
- Guest operating system support for Microsoft Windows 8 and Microsoft Windows Server 2012
- Support for virtual and physical machine sources with GUID Partition Table (GPT) disks
- Support for virtual and physical machine sources with Unified Extensible Firmware Interface (UEFI)
So I'd imagine we'll see it in the VMware vCenter Converter Standalone in the next major release, just can't say for sure when it will be!
