If you actually read that link you provided you will see that Hasbro Films has produced none of their properties into feature length films. It is a subsidiary designed to deal with the legalities of licensing films to actual production companies. You'll not that it is also on the hook for unproduced films for a hefty sum.
If YOU had read the link, you'd see that Universal paid a fee to drop that agreement, so Hasbro is not on the hook. (They were only on the hook for movies that were made, and only two of the seven were made.)
And that Hasbro Studios is one of the production companies of
[ulr=http://en.m.wikipedia.org/wiki/Jem_and_the_Holograms_(film)]Jem and the Holograms[/url], which is only distributed by Universal.
Really, though, it is sort of a silly argument. None of us know what is planned and what may happen. My only assertion is that Hasbro will not successfully turn D&D into a top tier brand outside of gaming circles and that resources directed that way are wasted, but I freely admit I hay be totally wrong and 2018 might be the year of the billion dollar Dark Elf international blockbuster hit.
I think Hasbro is looking at all of their brands and wondering what can be turned into mega-franchises and big hits. They're going with board games (
Battleship and
Ouiji for some unfathomable reason) but they have a lot of other properties they might consider.
I think D&D has a better chance Glo Friends, Inhumanoids, COPS, or Visionaries.
The question is, even if that were to happen, do you think it would actually benefit the RPG?
Honestly, no. Not much.
Comic movies are dominating the theaters but that has not translated into the success of the actual comic magazines.
A big movie might help D&D more than comics. D&D has some advantages. The D&D books are found in most big book stores, while comics tend to be ghettoized into comic book stores (aside from a handful of trades). D&D has a clearer entry point, and seems like a single one-time cost rather than regular pricey purchase. And there's less continuity to worry about working around, and other problems like crossovers and gimmick covers.
And if you could theoretically bring 10,000 new readers into comics, those readers will spread out their purchases, increasing sales of a handful of books by 2-5000; if 10k people came into D&D they'd all buy the same couple products: the starter set and PHB, which maximizes profits.
But while comics can be an individual purchase, D&D does require some group buy in. So that's a disadvantage.
But the
Lego Movie did amazing things for the Lego toys, and turned around the company's fortunes. So it's not impossible. Now there's a planned sequel and a Batman movie. D&D could easily follow that model and spin-off popular characters or explore different directions.
