i have heard that some of the RBN songs will eventually be updated to support keys and whatnot. however, lets say i bought a song off RBN and i use it on RB2, but the song eventually gets ''updated'' to support keys. will i still be able to play the song on my rock band 2? if they update a previous RBN song will they just make a second version of it instead of replacing the old one? and will the RBN songs that are ONLY compatible with RB3 be seperate in the playstation store?
because at the moment i dont really want to change to RB3 at all.
