Here is some information about Titanfall's 'prestige' system. Prestiging in the game is regarded as 'Regenerating'.
Max level is set to 14 in the beta files. However Level 50 is the max level in the final game.
There are 10 generation ranks. I believe generation 1 is what you start the game with.
Here is some of the menu text taken from the beta:
Take me to generation [next level].
Warning! You will lose all that you have unlocked and be reset to level 1. All challenges will be reset. However, you will earn XP at an accelerated rate of [XP RATE] as a [NEXT GEN NUMERIC] gen Pilot. You will retain your Burn Card collection, and the Ogre and Stryder Titans if you unlocked them. You will get a unique chip indicating to others your Gen status.
Years of battle have taken their toll. We can regenerate you... at a cost.
Your body can be restored. But your memory and your experience...all will be lost.
When you awaken you will respawn a [next level] generation Pilot.
You will be better, sharper, acquiring experience even faster than before.
Are you sure?
Are you really sure?
Would you like to go to the next gen?
Take me to next gen!
