I know of a few local businesses that still run off of Windows 98 SE systems, and one that still operates on Windows 95. Still over 30% of the planets Internet enabled PC's are running on Windows XP. It'll be years before that number falls below 10% I suspect just because XP has such fantastic market penetration.
Whether it's a big deal or not depends on the company. It will not be a big deal to smaller companies that use Windows XP for basic functions, but it's a big deal to larger companies that have a service contract with Microsoft and need timely solutions and support.
Companies can choose to run their systems on DOS if they want to. Microsoft dropping support for an OS is not going make it stop functioning, but Microsoft isn't going to sign contracts and offer support for a company that is running old OSs. It's just the way they operate. Is it a cash grab for them? Maybe, but it's the cost of doing business if you desire support from them.
You are right, XP still has a high market penetration, and it won't go away soon. I was still running XP on my desktop up until a few years ago, but after moving away from XP I would never go back.
