Glorious will do very well. I'd say it's near guaranteed the UK and Ireland's 12 points. It's not that similar to Euphoria, either, and even if it were, Cascada were doing this type of music well before Loreen came along.
Contenders at the moment are Norway and Denmark.

EDIT: British rumours, for those interested, are Diana Vickers, Amelia Lily, Shona McGarty (from Eastenders), Kimberley Walsh and Geri Haliwell. Apparently people in the know have heard that it's a female who would be loved by the gay audience, so that doesn't particularly narrow it down from any other British female singer. Then again, we were meant to have Pixie Lott last year until the head of the BBC delegation vetoed it and we ended up with Humperdinck instead.
