That being said, Hasbro's main interest is not families, or toys, or anything of that nature. Their main interest is making money. They will do whatever they see fit to make the most money possible.
Sure- thats true for every company, but what people miss when they say this is that every company needs a basic idea as to HOW they actually plan to do that; it's the thing that gets people interested in supporting your company.
People aren't just going to give Hasbro money for no reason. They have to fill a need that the people with money have.
In this case, Hasbro fills the need of families wanting to spend time together and do something other then watch TV.
And a company (especially one as large as Hasbro) doesn't change it's default mission statement at the drop of a hat.
My larger point, however, is if you look at what WoTC is actually doing, you can see it's in the exact opposite direction then going purely digital.
Look at the emphasis on in store play.
Look at how they've redesigned their products to include elements people want in a physical game.
Look at how they've lowered the cost of the physical products.
They're emphasis is on selling physical products, and using digital media to support that.
If they decided to go purely digital it wouldn't happen over night, and there would be signs showing they were moving in that direction.
All signs in this case, however, point to continued support of physical product.
