The type of "mature IP" that would be ideal for Nintendo would be something more like Uncharted or the James Bond IP.
Something that appeals to hardcore players (namely 14-35 year old males) without being wildly out of sync with Nintendo's reputation as a family company.
Grand Theft Auto is too ridiculously violent, it's just not a good fit with Nintendo's other franchises.
