Wow, really impressive work! Seeing projects like this makes me want to learn how to use the Construction Set and dedicate a few weeks to learning how to model. That would just play hell with my university grades :facepalm:
Are you working with Onra to make this mod compatible with the Tamriel Heightmaps?
I'm more than happy to give tutorials to begginers for the CS and for modeling, over MSN Messanger

And this isn't based on Onra's heightmaps, it's in it's own worldspace (there's also various conflicts that occur by having worldspace mods in the same worldspace as eachother, aka adding them into the Tamriel worldspace).
Before clicking the link:
"Oh, ANOTHER "NEW LAND COME AND SEE OMG!"-mod... yay -.-
Clicking:
"Hmm, this looks sort of decent. Several years in development... well, that can't hurt"
Pictures:
"WOW"
This certainly looks promising. Out of interest, how are you planning the development/release? Will you follow the "Release when done" approach, or release it in various betas with more and more added to the game?
Also, I read the interview, and this worried me slightly:
So you'll be re-recording the entire sound gallery of Oblivion, while also adding your own? That seems like quite a huge project to be honest =/
I don't think this is what they're going for. Rereading it a couple times, I think they're simply planning to record new rumors/grunts/etc for all of the NPCs added by their High Rock mod. This is so that a NPC that you meet doesn't talk to you in an original recorded voice when you ask him about a quest, and then talk in a vanilla recorded voice when you ask him about the latest rumors. Remember how, in vanilla, the beggars spoke in different voices? They're trying to avoid that sort of thing.
We hope to release a Beta at some point, but for the most part we go by "it's done when it's done", so we don't have a strict timeframe for releases.
And Fiore1300 is right, we aren't re-recording all the dialogue in Oblivion, only re-recording the minimum of what you need for a 'new' race (grunts, Disposition game responses, etc), which isn't more work than we can handle, and means you don't got switching between vanilla voices and High Rock's, similar to the affect with beggars.
