Just as Yoichi Wada left the flagship earlier this year, it's presumed that not meeting sales expectations for the major releases over the last year doomed Fischer's tenure, though I'm hearing that the expectations being quoted were a bit ludicrous to begin with. There are also rumors that there may be big shakeups coming in North America relative to the mobile release strategy or even that entire division of the company; this could be the sign of an executive getting his golden parachute as the plane goes down.
The most recent "big" game from the North American division was last year's Quantum Conundrum.
