Basically, this is what was said:
If true, we'll have an Adeptus Titanicus game released sometime this year, and we'll have Knights accompanying the three main Titans. This will be awesome! And billions of infantry! I can't wait!
I'll keep an eye out on more news, and let you guys know when that happens. Oh, and another great news is that there will be a Horus Heresy novel written from the perspective of the Imperial Army, so that's also something to look forward to. For now, I had best finish the Gaunt's Ghosts novels and hopefully get started on War of the Fang. Just praying for more Imperial Knights, Imperial Guard and Thousand Sons novels, along with Adeptus Titanicus.
