In his most recent blog, Owl City stated that his new record will be released in August. He also said it's going to be very different than his previous stuff focusing more on his influence from European trance.
This actually could be great. Those are the exact same artists in this genre I listened to as well. I still haven't found anyone new who does this style better than ATB. "Made of Glass" is such a classic.
Oddly it was the clear euro dance elements of Ocean Eyes that made it a listenable album for me. I'd rather hear more of this from him and less sappy lyrics about going to the dentist.
