You mean, 40K Relic's games are dead. I don't think there would be an issue if CA decided to release a Total War based on 40K or another devs to work on something like SP space marine.
Which 40k game does good and aren't dead again?
Its not Eternal crusade.
Its not Space Hulk Deathwing.
Its not Battlefleet Gothic Armada.
Its not that other Space Hulk game.
Its not Sanctus Reach.
Not Space wolf.
Not Armageddon.
Not Rigicide.
Not Deathwatch Killteam.
While Inquisitor Martyr is not out yet, its going to be a MASSIVE surprise if it won't die within 2-3 months given what it offers and how massively bugged and content lacking it is(they want to release it before end of March).
So, you say relics 40k is only dead?
Till we see any teaser with some gameplay, i'll hope they don't make the same mistake as with AoE3. I mean, someone on MS should tell them that:
