Could we just get one thing straight? This young girl is not an opera singer. Nor is Paul Potts. Nor is Katherine Jenkins. An opera singer is someone who sings an entire staged opera in the theatre without a microphone. Of course there are classical singers who confine themselves to the concert platform, singing Lieder and orotorio, but they too sing without microphones and have the technique to sustain an entire evening of singing.
Having got that off my chest, she is obviously something of a prodigy, with a naturally beautiful sound, the voice extraordinarily well developed in one so young. That said, there are a few problems of support (well she is only 10!) and she is singing material she would be wise to leave alone for now. She should be being nurtured by a good teacher, not being subjected to this kind of exploitation so young. No doubt she will be sung out by the time she is a teenager, but in the meantime the marketing people and the record companies will have made their money and that will be the end of it, which is a shame because she obviously has talent and another potentially great voice will be lost to us.
