AFAIK, there is no difference between PS3 and Wii version.

The only difference I know for this game:

The Xbox 360 version of "Rock Band: The Beatles" has an exclusive song (All you need is love) which the PS3 and Wii don't have; but the song is available for download on the Wii and PS3.

  Water ionization becomes much less evident if the hydrogen bonds are just a few percent stronger but pure water contains considerably more $\ce{H+}$ ions if they are few percent weaker.


I found this line in some article. You can even copy/paste this line on search bar of Google. I didn't understood the latter part of this statement which is "but pure water contains considerably more $\ce{H+}$ ions if they are few percent weaker". The author is indicating to which of the following three situations?


only $\ce{H+}$ ion concentration will increase 
both $\ce{H+}$ and $\ce{OH-}$ will increase 
$\ce{H+}$ will increase and $\ce{OH-}$ will decrease that is the equilibrium constant remains same.
