A Criterion made Forza game would be interesting though, speeding through oncoming traffic and badass crashes.
The leaker has said that MS will reveal most of what he/she was leaking in March as well as E3. So i guess it won't be too long before we learn if he/she was full o s*** or not.
I hope that won't all announcements though, cause there should be more. All these mentioned games except for Forza Horizon 2 and Crackdown 3 were officially announced already. Rare can't be sitting still and what other new IP they got planned.
