It depends on what firmware packages are available at installation time, which in turn depends greatly on which installation image you use. The netinst and DVD images that are linked from the Debian web site do not include any non-free firmware. But there are unofficial netinst images which *do* include the non-free firmware. If you use one of those, you're very likely to get some non-free firmware installed for you automatically, if your computer has any devices which want it. Almost all new computers do. Laptops especially.
