We asked game director Ian Roxburgh and lead designer Jim Whitson The Creative Assembly a bunch of questions on the new Mortal Empires campaign for Total War: Warhammer I & II, and also managed to sneak in a question on 40k.
It's not a far stretch of the imagination that we could possibly get a Total War: Warhammer 40,000 after the fantasy-trilogy is completed. Afterall, sister studio Relic released Warhammer 40,000: Dawn of War III earlier this year, and while it would be two 40k strategy games, they would be different enough not to really compete head-to-head all that much.
We asked if that might be a possibility and got the following reply:
"At the moment we're flat out on all this additional content for Warhammer II and finishing this trilogy with a bang. Beyond that, nothing is set in stone but personally, we'd love to do it."
