I didn't actually find how many were developers vs. secretarial, etc. but constantly reading headlines like this over the last few weeks sure makes me nervous about trying to find work.
I worked at EA from 2007-2009 until I was part of what starting to seem like an annual 10% workforce reduction, it's par for the course with them. I'd recommend working for a privately owned studio if you can, it doesn't remove the risk of going to a sweatshop that crunches nonstop but you don't have to worry about getting laid off because of earnings calls or another project you have no control over failing.
