No, Master Chief is NOT in Halo: ODST.
This shouldn't discourage you from playing, however. It is a very fun game and the perspective from an ODST (Orbital Drop Shock Trooper) and the storyline employed are quite intriguing.
He was a Spartan before reach fell but master chief wasn't well known until after reach fell and he was the last Spartan
yes but only through a Easter egg

Yes, but it will take a long time. He and Cortana went through the portal as it closed so, they got cut in half. Then, they have to go back to Earth by floating back. Master Chief went into the stasis chamber and Cortana put out a beacon.
The Master Has Come Back was created in 2005.
A Halo 4, also known as Halo: Reach, will come out in the November of 2010, and no, it will not follow the Master Chief's story. You assume the role of a SPARTAN-III.
yes he actually never did watch after the credits for halo 3 or watch the halo 4 trailer.
Halo: CE.
Yes, the Master returns in the Christmas specials.
Because at the end of Halo 3, Master Chief and Cortana don't make it through the portal in time so they are left drifting.
I have heard rumors that Masterchief is supposibly the security guard from Marathon. That Masterchief was the one they picked up i nthe pod. No idea if it's true or not though.
Yes and master chief comes out naked at the end and has a big hairy wiener
