Depends on the numbers you believe are accurate - A lot of smart people say the government and BP are giving very very low estimates.
But even if the BP/Government numbers are 100% accurate (And they've gone from 1k day, to 5k a day, to 20k a day...), we're going to almost certainly eclipse Ixtoc.
Relief wells won't be ready until July/August, and then it will take time for them to actually stop the leaking. 6 months to a year are the numbers I read on TOD, which has been pretty spot on on everything else so far.
