The Rock Band series has reformed and come back with Rock Band 4 due out for later this year.  Harmonix has officially confirmed that its releasing Rock Band 4 for the PS4 and Xbox One consoles. The game will be out later this year and promises to add even more new features to the beloved franchise.  Rock Band 4's instruments will now be made by Mad Catz. Harmonix says the new game will still be familiar to fans, but they will also be expanding the franchise to entice new players as well.  Harmonix is working closely with Sony and Microsoft to ensure you can use your old instruments for Rock Band 4. They're hoping you will be able to use your old instuments on the PS4 and Xbox One consoles. It wouldn't be fair for players to spend hundreds of dollars again for the same instruments.
