Nintendo has 36 Months to produce something Eternal Darkness related to keep the Trademark
Looks like Nintendo is going to have to put up or shut up with their Eternal Darkness trademark. The USPTO has seen Nintendo's request to extend the Eternal Darkness trademark, but has responded to that with a Statement of Use or Extension Request. This means Nintendo has 36 months to actually do something with Eternal Darkness, otherwise they'll looks the trademark request. Well...things just got really interesting!
I think they might do HD remake or port just so they can keep the trademark.
