Pineau should give half his prize money to Arashiro, he rode in true kamikaze style from 1500m out and saved the break.
The chase was wierd, it seems from looking at the live report that Columbia and Garmin didn't help Lampre or Liquigas with the chase early, which was why the gap was still a minute with 7km to go. Then Columbia, Garmin and Sky panicked and threw all their guys on the front, going full gas, and burned them all out in 5km without bringing the race back, so the chase actually slowed down a bit going in to the final few kilometres. By the time the pack reached the finishing straight all the organisation was gone and they were weaving back and forth across the road.
