NACAC officials have announced that the "topic of your choice" option in the Common Application long essay will be removed, leaving applicants to choose only from the given list of topics. This has been reported here at the Chronicle of Higher Education and has also been written about here in the New York Times popular The Choice column.
ps. I strongly encourage current and future undergraduate applicants to follow The Choice blog at the New York Times, as it regularly contains useful information on the process of applying to universities.
pps. Are there any potential undergrad applicants out there looking for an essay or admissions counselor? Be wary of those that make promises that seem to be too big or too good to be true, as another recent article at The Choice shows.
