In an interview with MCV magazine, Harmonix product manager Eric Pope confirmed that Rock Band 4 will be released this October and will run at 1080p resolution and a steady 60 frames per second.
“It’ll be 1080p and will run at 60fps,” Pope said. “I know there’s a vocal group of players that want to hear that. But what to me is more exciting is the online infrastructure of the consoles. It will open a lot [of] opportunities for us to support the game in more reactive, timely ways.”
In a different article in the same issue, MCV wrote, “Rock Band 4 is now set to return this October, and widespread reports claim that Guitar Hero is also braced for return.”
