I trust the legimacy of that unless they post an interview with him soon. Why would an LA music blog talk to Josh while he is in Europe on tour when there really isn't any new news to discuss.
My guess is they read a post on reddit about some kid who met Josh after the show and Josh told the kid TCV would be doing another album after Queens. DOn't really know the context of the kid talking to Josh and what he posted online afterwards.
Either way, not exactly exciting news to me. TCV is the least exciting band he's been.
