Reports this evening assure us that despite news to the contrary, the exclusive downloadable content for IV is still on course to arrive this side of Christmas.

UK site Eurogamer.net report that the content will actually be made available on Live come November, which will come as a relief to gamers concerned the new content might slip into 2009.

Two episodes will be released for the 360, approximately 10 hours in length, while new achievements will be offered. No pricing has been offered, and it isn't clear whether the new content will be comprised of new missions and plot; or new cities to explore.

Microsoft apparently spent 50 million USD landing the content exclusively for the Xbox 360. We'll keep you posted.
