I think the biggest problem with this confirmation, as far as its validity is concerned, is the almost completely theoretical nature of black holes. I have no doubt the stars are rotating, and it's rather likely that it's a black hole, but until we can actually measure the properties that define what a black hole is, this can't really be called a confirmation. It's more like... a very certain speculation.
