Regarding the 50 million figure, it is notable that that is what 4e failed to hit despite a comparative fire hose of product relasease and DDi (well, "50 million with a clear growth path to 100 million"). 5e seems to be going for lower costs and higher returns on each product, but probably has lower annual revenues overall than 4e at it height (albeit much more sustainable over the medium term).
Which means 50 million seem rather optimistic. Maybe if/when successful movie/Netflix/etc deals actually come to fruition, but nothing much has actually happened yet on that front.
