didact idea

for those of you who have read the halo books(especially the forerunner saga) will know that the third book silentium, will be released early-mid 2013, and seeing as though we dont know the final storys to the didact and bornstellar(for those of you who know who that is) and i wan just thinking, the diadact we encounter in Halo 4, was that indeed the original didact, or was it bornstellar?
It would be great to hear your opinions/ideas.

sorry for the diadact in there( obviously meant to type didact)

I strongly believe it is the Ur-Didact in Halo 4.
