Odds the same, but the number of encounters up to nine.
From http://neo.jpl.nasa.gov/news/news149.html:
"The asteroid's motion subsequent to the 2029 Earth close approach is very sensitive to the circumstances of the close approach itself and a number of future Earth close approaches will be monitored as additional observations are received"
So after 2029, all bets are off, well need to recalculate the trajectory.
