Yes, they are an incredibly well-oiled machine. An old friend and former colleague of mine is one of their producers and development executives, and I can say without hesitation that he works harder than anyone else I know in that business. Marvel is in a state of continuous production on all of its properties, all of which are centrally coordinated. This wasn't always the case. Historically, Marvel has had different licensing deals set up at different studios: X-Men and Fantastic Four with Fox; Spiderman with Sony; etc. When it set about creating the Avengers initiative, it realized the logistical benefits of keeping everything under one roof. The Disney acquisition helped with that. The company still does projects under the terms of its legacy deals (see: the Spiderman reboots still being made at Sony, presumably at Sony's request, to exercise and thus keep its deal active). But the magic seems to be happening with the more centrally coordinated projects, like Thor/Iron Man/Cpt America/SHIELD/Avengers.
