Yep that's the one. I know it doesn't say Dawnguard but Ready at dawn stuck out to me..
I think you misread that. Ready At Dawn is the name of a development team that has been developing the PSP God of War games, so Ready At Dawn isn't a reference to this Dawnguard project. That said, Dawnguard will either be the name of an expansion for one of Bethesda's games (like Skyrim), the working title for a sequel to a game, or it will be the name of an entirely new IP. So right now, we can only speculate what Dawnguard will refer to, but Dawnguard sounds rather fantasy-like, and to a stretch sci-fi, but if this refers to one of Bethesda's already established IPs, then it could be TES-related since Dawnguard doesn't sound all that Fallout-ish ( I'd imagine Fallout 4 will probably just be called Fallout 4, and a Fallout MMO would probably have a subtitle that references the MMO part, which probably wouldn't be Dawnguard, though I'd rather just they do Fallout 4 for the sake of fans), but like I said before, Dawnguard could easily refer to a new IP as well, though I can't imagine them starting up another fantasy IP when they've got

, and besides, they probably are going to hold off a bit on new IPs for a while anyway. They've already got Dishonored in the works as a new property, and they're probably going to work on popular IPs for now so that
A. They won't end up in the hole and
B. So that they won't alienate their fans by neglecting their properties like what some companies (which I shall not name) are guilty of.
But since Dawnguard could refer to anything (including Fallout and new IPs), I don't really know what it will be.
