摇滚乐队将在今年晚些时候进入下一代的游戏机，虽然我们不知道更多的其他，Harmonix明确表示，（几乎）所有的歌曲，你购买了过去的摇滚乐队冠军将继续摇滚乐队4。这也适用于你的硬件-大部分，无论如何。以下是我们与Harmonix项目经理Daniel Sus**an谈话的相关片段。

We are working very hard to port all of the songs that we have had in our library forward to the Xbox One and PS4, and that's a time-intensive process, we're actually taking a library that took us five-plus years to accumulate, and we're doing all of that work in a very compressed window in a matter of months. How many songs is that? It's over 2,000. It's a big number. So it's our hope that players have access to the full catalog of music that has already been licensed to this game. Only a very **all percentage actually own everything... but there are a lot of people that have bought lots of songs already, and to those folks we want to make sure your library of songs on the PS3 will carry forward to the PS4 and same on the Xbox 360 to the Xbox One. Not cross platform? Not cross platform. I wouldn't put the stake through that, but that's the one that would take a lot of support from Microsoft and Sony, and frankly that's a political rat's nest. I don't see it. And we have our hands full just getting everything up first. So building a library is kind of the first step and respecting the entitlements that people have. All this — the legacy hardware and the legacy tracks —by launch? By launch, yes. The one hedge there has to do with the volume of songs by launch. It is a process, and we have to go through all of the submissi*** process which includes [quality assurance] to make sure that nothing's getting lost in the transfer. So the number of songs at launch is directly proportional to the time it takes to get a song up; the challenge then is just dealing with the immense volume of songs that we're working with.
