I think there's a decent gap where it doesn't make sense economically to download and run your own OSM tile server. Especially if you need worldwide coverage, the costs of keeping a tile server with a full dataset running plus a redundant spare can easily exceed the cost of paying someone a couple hundred dollars per month to do it for you. There are hardly any services like what MapBox and CloudMade have. The closest seem to be the various consultancies that will design and host a map for you.
