I highly doubt Criterion's next game will be shown for a while. 80% of the staff were moved over to Ghost Games UK (and then fired when it was closed down) and the two founders quit.
They said they were up to 25 as of the IGN interview though, and they're hiring a lot, so what are the rest doing?
30+ feels a bit big for a mobile title.
I mean one of the postings asks for "Extensive vehicle art experience on current/next-gen consoles and PC." and another is "We have a fantastic opportunity for a Senior Grpahics Engineer to join the Criterion team and take our graphics system to the next level, developing visual effects and cutting edge graphics for our unannounced next-gen title." which isn't 100% out of the question for mobile but it's kind of a lot to ask
Them dropping the mic after announcing they're giving DICE all the time in the world to do Mirror's Edge AND Battlefield to where they aren't buggy messes would be a megaton, personally.
