That was quick! I don't think there will be mudslinging like their was under previous circumstances, though.
"Tarja rejoining the band..." et all, ad naseam, ad infinitum...
"Wish"ful thinking. That (hopefully) will not and will never happen. Of course, the Tarja fanboys are going to be harping on this news story and getting their tightie whities in a bunch over speculation that that will indeed happen.
This is like the Arch and Di'Anno fanboys venting their continuous hopes over 20+ years that their respective bands will get their original vocalists back...

That said, Nightwish the band is far better (and more successful) with a vocalist who isn't showing off their operatic vocal chops, piercing eardrums and shattering glasses at all stops. If you like Tarja - listen to her solo CD's. All the interested parties have moved on.
Regardless, the 2 shows I've seen of Nightwish this year were great, their last 2 CD's were great, and hopefully they'll work this stuff out behind the scenes, away from the trolls and drama-loving Blabbermouth and Tarja fanatics.
Regardless, this sucks. Should be interesting to see where they go and how Floor fits into the band... Back to the musical drawing board!
