Peeved
They've been announcing this with similar vagueness for over a year now I think, I consider it vaporware unless I see one in a shop with my own eyes, and I don't see that happen really, for some reason gigabyte doesn't want to update the x58 platform currently.
In their defense I'm going to guess they are waiting for statements from intel to solidify, seeing they get info early and if they were told there would be some x59 or something (VRD-12 perhaps?) they might be holding introduction to avoid having a production line of expensive boards and have intel a week later come with a new chipset revision that is required for the next CPU's.
