I absolutely think GW is going to be in serious financial trouble within a few years if not sooner. They seem to be in full court press mode now, promoting maximum opportunity for short term sales at the expense of things that might help them even in the medium term (for an extreme example, they didn't take an extra day to make sure that their most recent codex is capable of surviving turn 1 before putting the $41 book up for sale).
But, looking farther out than that, since GW completely pulled out of being involved in the actual running of their games, they now have no way to stop the digital printing revolution from invalidating their entire business. Once people can 3d-print their own terminators, GW gets hit right in the junk. In comparison, Privateer press requires usage of official models at their events, and they have a business relationship with basically everyone that runs a tournament for them, so this is capable of being enforced.
