Sony has filed a trademark for Twisted Metal in Europe. The filing is a community trademark. The last Twisted Metal game was released in 2012 for the PS3.
This trademark is for computer games, toys, and electronic game services provided by the internet. This means that this might be for just toys. This might suggest that there is a game coming in the Twisted Metal game series. We probably won’t see anything for years if there is a game planned down the line. If there is an actual game in development, don’t expect news for some time.
