With the addition of Panasonic to the full frame mirrorless crowd, they've also announced the expansion of their Lumix PRO Services program to a few areas outside of Japan (e.g. US, UK, Spain, France, and Germany, with Ireland and Austria to follow).
The pro service programs vary from company to company, and generally have minimum equipment requirements for eligibility. Some, like Panasonic's, also charge a yearly fee, while others, such as Nikon's, are free if you qualify.
