Microsoft also stated they are no longer working with Reagent Games and is now working with Sumo Digital. Crackdown 3 was also going to use Cloudgine, a cloud based processing system to process the destructive elements of the game. Cloudgine was acquired by Epic though in January and Microsoft isn't specifying which cloud computing service they are using for Crackdown 3. Cloudgine was co-founded by the founder of Reagant so they are pretty closely tied together.
So where does this leave Crackdown 3? Microsoft showed the trailer at E3, but that's about it. We'll see if they hit their latest release date again, but I wouldn't be surprised if we hear another delay or even a cancellation of it.
I was hoping Crackdown 3 would be a return to form of the original one as I was a big fan of the first game, but the more I read about its problems, the less I'm looking forward to it.
