Longtime series developer Harmonix Music Systems has announced that they will be releasing Rock Band 4 this year. It will be launching on both PS4 and Xbox One. Rock Band 4 will have 2,168 available in game.
Harmonix CEO Alex Rigopulos said:
“When we stopped developing Rock Band 3 [in 2010], clearly the market needed a break. But since then we’ve been paying close attention to what our community has been saying about it. There’s been this steadily growing crescendo of fans saying, ‘Hey Harmonix, what the hell? It’s time! Why haven’t you announced a new Rock Band? We’re ready for it!’”
Fans of the series fret not (heh...fret) your purchased songs from pervious Rock Band games will transfer over to the new generation consoles. However, you will not be able to cross platforms, so for example if you bought Xbox 360 DLC you won't have it on the PS4.
Unfortunately Rock Band 3's on-disc music and the The Beatles: Rock Band music will not be in Rock Band 4 due to licensing restrictions.
There are a few other things to note. Harmonix is currently trying to make Rock Band 4 compatible with previous controllers, so the people playing their game don't have to buy new ones. The old controllers don't work right now because the newer consoles use a different type of wireless connection than previous consoles.
Lastly, Harmonix has no intention of releasing yearly sequels that will saturate and destroy the market (like they did before). Well, thank you Harmonix. This means that not only are you making this game for the gamers, but you are going to make it well and not half ass it.
