$50 for the game. Flat. Pricing open enough for 3rd parties to charge $60. Maybe a model somewhere for $40 cartridges that play handheld and console, but an upgrade option for downloadable higher quality assets on the console for an additional $20.
Yeah, NX could introduce a more flexible MSRP software pricing scenario at retail than we've seen to date, but splitting the difference between handheld and console game prices at $50 flat for the baseline pricing for games sounds right. I mean, it's not like developing handheld games is getting any cheaper anyways, even with Nintendo pooling their developers together.
The upgrade path erodes the nature of owning a physical copy, though, and puts them dangerously close to Xbox One-level backlash territory.
brothers sounds closer than PS4/Vita - more like ipad/iphone, and iwata has referenced ios as well I think? But you're right that a literal hybrid may require too much compromise for either the handheld or home console.
Will be interesting to see.
Yes, Iwata has specifically stated that the "ecosystem" design ethos is being modelled after iOS and Android. It's rather difficult to not see a shared library scenario when that's what NX is being modelled after. So Nintendo would either have to cut physical media for their platform completely out of one of its selling points and make this advantage an eShop-only thing (which would be a mistake) or find a way to unify the physical media back and make it part of the selling point.
