Scalebound being cancelled had more effect on Platinum than Bayonetta 2 and W101 bombing. The games came out, Nintendo at least paid the company for their contract work, while Scalebound was in development for 4 years and will never see the light of day, that's a huge blow to a company.
Bayo 2 and W101 can/will probably be ported to the Switch, which would end up increasing their overall sales. Scalebound will never have that luxury, nor will they probably ever be able to restart development on it due to JP leaving and the nature of their contract with Microsoft.
