The Sony Playstation was originally conceived as exactly that: https://en.wikipedia.org/wiki/Super_NES_CD-ROM Part of the issue with these sorts of console add ons is that they just split the addressable market further. ISV's either have to address only console owners with the add on, or they can address everybody with the console if they can manage without the extra hardware. Commercially, this can be a hard sell, which makes it difficult to sell the add on, making it even more difficult to write software requiring the add on. |

No add-on has been able to survive more than one year outside Japan. Not even PS VR, whose sales are too low.
