There are actually a fair number of industry professional developers (including L. Spiro) in the community who have access to dev-kits through their work.
The difficulty and cost involved in access to dev-kits is a big part of the reason PC (and mobile, which is a very popular target you left out of your original question) is so popular as a target for home, hobbyist and indie projects. There also tend to be more publicly available resources for learning to target PC.
