I don't really see how they could do anything but support HTML5. It doesn't exactly seem like a concession, or anything that would have been in any doubt to begin with. Their product is a web a development application. HTML is the primary markup language for the web.
Unless the point being made is that it could potentially have been substantially delayed. But I still don't see how this would have made much business sense.
