@Shaz11 - Awesome, awesome signature pic. (Is that what that's called?)
OT: If any negotiations took place, I suppose its possible Punk requested a match with Taker once he knew he was going to drop the title to The Rock. But, actually ending The Streak? No - at the end of the day, getting to be THE GUY chosen to fight Taker is the big reward. He's already won by being Taker's opponent.
This time every year I mention the potential of a draw, perhaps both collapsing for more than 10. Both men push each other to the limit, the opponent "ends the winning streak", but Taker remains 'undefeated.' 20-0-1 has a certain ring to it, I suppose.
