Konami revises their "no chance" stance for Metal Gear Rising: Revengeance having a Wii U port. The new official stance is they won't consider working on one until there is enough demand for one to be made.
Its also rumored Platinum Games wants to work on a Wii U version since they've gotten a bit cozy with Nintendo recently but Konami doesn't (or won't fund it).
