In terms of probability the Lion seems certain to return as he is sleeping intact inside the Rock only waiting to be awakened. Leman Russ is also a good bet given that he has (possibly) been sighted during the 13th Crusade. Besides I wouldn't believe a Space Wolf dead until I'd counted his bones. Neither Primarch was exactly noted for his organizational genius. And getting them to work together might be a serious problem for somebody. Vulkan is another good prospect as he apparently disappeared voluntarily and promised to come back once his conditions were met. He strikes me as a useful person to deal with Mechanicus. Corax and the Khan are more problematic as neither has been heard from in ages and both are in decidedly unhealthy places (the Eye and the Webway) still it is far from impossible that they have somehow survived and either make their own way back or are found by their Astartes.

Dorn and Gulliman, the organizational geniuses, are REALLY problematic since there is evidence that one is dead and the other is in stasis. Of course it's possible that Gulliman really is miraculously healing (I know it's supposed to be impossible but this is 40k) and maybe those bones aren't Dorn's after all (in which case where has he been all this time?). Frankly I'd like to see Dorn back but I'm not so sure about Gulliman... and the probability of those two co-operating is slightly lower than that of the Void dragon taking up macrame.

And then there are the two missing Primarchs. Maybe I'm reading too much into it but the exchange between Dorn and Malcador ('if only it were fifteen' 'they are lost') sounds to me like the Primarchs and their legions are out of touch either exiled or fled rather than dead.
