Well this seems a bit sudden. Right after new DLC launches for Hyrule Warriors Legends, it appears Nintendo has now abandoned their trademark application for “Hyrule Warriors”.
The reason given for the abandonment, according to the USPTO website (spotted by the hawk-eyed folks at NeoGAF), is “because the applicant failed to respond or filed a late response to an Office action.” Now, given this information, it’s a possibility that this is just oversight rather than an active choice on Nintendo’s part, although it would be very odd for them to make such a mistake.
If this is indeed an intentional move, then this could mean that it’s unlikely that we’ll see another Hyrule Warriors title in the future. With all the content pumped into both titles, it wouldn’t be surprising if Nintendo feel there isn’t much left to add to the series.
