The primarchs will come back and I believe that the Emperor will be reincarnated. The Imperium will break up into several factions since they can no longer maintain contact. Ultramar will hold out for quite some time. Chaos will probably reach Terra and they will fight the mother of all battles with the Grey Knights.

Tyranids will utterly destroy all. Although, I have been thinking that since the Hive mind is guided by the Astronomican towards Terra, once the the Golden throne fails will the Hive mind be able to locate Terra? In my most heretical thoughts I have thought that the death of the Emperor would save the Imperium from the Tyranids.

I would flee to Tau space and join them. Of course once the Emperor was reincarnated we would have to find him...Chaotic forces would be looking for him too. The Inquisition would execute the "faithless" by the billions. The returning primarchs would save us, but just barely. The Emperor would do battle with the C'tan and maybe Khorne or Nurgle. I imagine the Eldar would help humanity a lot.
