‘Rock Band 4’ Is Happening In 2015, For Xbox One And PS4
The tyranny of plastic fake instruments is back: Rock Band 4 is happening.
Developers Harmonix announced that the music-themed game would return for Xbox One and PS4 in 2015 — and that it will retain the same button-drums-and-microphone based gameplay of the original.
Your existing instruments will work, and most of your DLC songs will also transfer, if you have any.
Eric Pope from Harmonix said:
Rock Band 4 will be the first game in the series since Rock Band 3 in 2010. More details will be released at E3 in June, along with a (rumoured) announcement that Guitar Hero, by rivals Activisionm is also making a comeback.
