I think it will be repealed sometime in 2014-2015.
So you are predicting a Romney win? As long as Obama or another Democrat is in the White House, they will veto any attempt at repeal.
Repeal in 2014-15 would mean a Romney win with a narrow Democratic senate in 2013. Republicans would almost surely flip the senate in 2014. What would be really interesting is if Democrats picked up the house in 2014 while losing the senate, then you have Romney in power for 4 years and Obamacare is still in effect...
