Shinobi could be a good candidate for this, Ninjas tend to be a good/safe sell.
Though if they want to sell games with this stuff (especially with movies), hopefully they don't pull what they did with the Marvel movie licenses/Sonic Boom and give the job to dubious development teams (or in Sanzaru's case a crappy schedule)...granted Next Level Games was probably the best of the bunch (Heck they're working exclusively for Nintendo now).
However, I imagine things may turn out more like the Bayo 2 and Bloody Fate.
