Well in regards of the Vita, the investment would also be worth it in regards to keeping existing owners happy. The last thing Sony want to do which the market is in such upheaval is unnecessarily alienate currently happy/loyal customers through just throwing the system in the trash.
Brand protection also needs taking into account. At least if they make some Vita exclusives, they can also release them on PS4 12-24 months later and recoup more of the development costs.
