Hasbro should take note of what Nintendo is actually doing. While the toy market is decreasing, Nintendo actually wants to break into it:

I actually think Nintendo is on the right path here. They are basically aping Skylanders but with neater figurines that actually have a purpose within any Wii U game.
If Hasbro were smart (Yeah..

), they would be doing something similar by incorporating chips into their toys so they can be scanned online onto games. The potential would be limitless as they could have 'make your own episode' apps in which you scan characters in or simply have decent video games in which you can play or interact with your favourite characters.
If they want to keep it simple like Nintendo are first starting off with, juts have them as virtual Trophies you can show off on social media as owning once you scan your toy.
The gimmick would be totally non-intrusive to the toy design and reasonably cheap to execute since the chip would be tiny and only contain what is basically a code with numbers.
There you marry both the digital age and physical toy interest back into the children mainstream. However you need forward thinking and willingness to innovate which Hasbro apparently do not.
