Well I think it is a bad day for rock and metal in general because despite their widening of the genres of bands that they signed, Roadrunner was at it's core still a metal label. Now they are being rolled into the bigger Warner corporate machine so who knows how that's going to change things.
But long term I just reckon that the major labels will drop everything other than their high-sales chart artists and the music industry will be further homogenised in favour of X Factor, radio friendly stuff that sells.
All extreme music or anything that isn't mainstream enough will just fall to the smaller labels/independents. Nuclear Blast (not that small), Peaceville, Season of Mist - all of which are European incidentally.
But how long can the smaller labels last when sales keep falling?
