This though also varies greatly depending on what we're talking about... Put VOTC Han out now, and he's almost pure profit to Hasbro. Repaint the E3 Jedi Fighter, and the same... The fixed costs are in, so those items are just gravy.
That's a really good point. All depends on how you calc your return on investment. If they still consider development costs of an older figure as part of the total cost to make a new figure, then ROI wouldn't be that much better. But to JJ's point, a lot of this is already sunk cost. In cases like this, they should be making much more profit on re-issues than anything new. Funny to think that the new TAC stormtrooper was likely less profitable than the reissued shadow stormie.
