I posted this in another thread... but it's applicable here. I do not have any "insider" info, just what I hear. So take this as a grain of salt!!
There is some bad news regarding the PIs - a great deal of PIs were cut for the Spring 2009 program because of the economy. The few that were offered were done so if the specific department budgeted for interns.
My department houses all Animal Program, Epcot Land/Living Seas, and Learning Solutions interns - that's something like 50 interns. My supervisor said that at this point she does not know if any of those will be offered for the Fall, it depends on how the budget works out, so she will not be posting them anytime soon. She hinted that the other departments are probably facing similar issues.
My fellow intern asked about extending his program or applying for new internships when they are posted... her response was IF they are posted.
