Line-up is quite great if you ask me (but I'm a icelandic BM fanboi hehe). But I already saw more than half of these bands (sometimes 3 or 4 times already) and the rest I'm not that interested. Plus these type of bands tend to tour and play at similar fests, so not that much of a loss.
If I ever visited Iceland during a fest, it would definitely be Eistnaflug.
