As for Hasbro's financials... I don't worry about Joe too much. Sure, they might have to scale back on the number of accessories or something to cut costs, but in my head, they'll always have to do far worse to Marvel Legends and Star Wars because those have license fees on top of them. I could see Hasbro letting those licenses go, in all honesty. Hasbro got the idea that every SW figure had to be a D+ tie-in or Lando, that's it. Same handful of SW figures have been there for months. Same with Marvel Legends... why bother if the stores have no interest in carrying them?
The truth is, other than Transformers, hasbro doesn't dominate the blue aisle nearly as much as it used to. SW gets four pegs, Marvel gets four pegs, GI Joe gets two pegs for retro Lady Jaye... and the rest of the aisle is like three different MOTU lines (I can't even keep track), Pokemon, WWE, weird japanese video game tie-in stuff, minecraft tie-ins, Godzilla... heck, even McFarlane's DC Multiverse stuff gets like six-to-eight linear feet at WM, way more than it can possibly justify sales-wise.
But Joe in general has to cost less to produce being an in-house IP. I don't see anything bad happening to it. But IF they simply produced what has been announced and then said, that's it, we're done... I think I'd accept that. Sure, I'd be pissed that there are still half of the O13 left and cool guys like Sci-Fi and Blowtorch, but they've covered the basics very well and given us a ton of characters, a ton of parts for custom fodder, and overall exceeded my expectations after getting away from the video game aesthetics.
Plus, let's not forget that Joe is licensing to other companies as well, like Hiya and Super7. And that's pure gravy, no effort on Hasbro's part.
