RUMOR: Another single next to Radar?

Remember the Born to make you happy/From the bottom of my broken heart double single release? There are rumors that Australia, for they already released Radar last year and don´t want to do it again, will get another single as fourth single from Circus... Wich one it´ll be is not decided yet. I think it would be great if Europe would get a double-single... Like Radar and a ballad or something... This would mean two great videos :D Hope it´s true...
