Or we get back on topic and don't feed a troll.
Personally I would love to see more progression storywise in 40k as a whole with Abby and the Emp. and whatnot. I just don't see them going to far though while they are still making money off of the current stagnation.
Honestly, I'd like to see the following happen into 41K.
Ghazghkull Thraka beams into the Emperor's Throne Room and pops him so that he finally dies, blotting out the Astronomicon and setting the Imperium back a few thousand years.
Leman Russ comes back and unites the great companies of the Wolves with the cure from the Tree of Life to find out Ghazghkull Thraka has killed Papa Empy and declares a Great Crusade against the Green Skins.
Lion El Jonson comes back and the treachery of his actions are revealed, Luther is exonerated and the Dark Angels sink into Civil War before Cypher shows up and executes both of them.
Robute Guilliman heals, comes out of stasis, rallies all the Ultramarine successor chapters under his banner and he unites the Imperium after over throwing the High Lords of Terra to reinstate his Father's vision of the Imperium.
That's all I have for now.
