> the new adventure promises to clear up confusion surrounding the fate of the Master Chief and his AI companion, Cortana
What confusion would that be then? Does nobody watch games until the end of the credits any more?
The Chief's last words were "wake me when you need me" - words which were seemingly aimed at Microsoft, given all the "this will be Master Chief's final adventure" spiel in the run-up to Halo 3. (A precedent which presumably means that Commander Shepard will return in Mass Effect 4 in 2016.)
