Tedder played a significant role in SoI, didn't he? That album had real potential--a little less polish and it could have been great. They overcooked it, though.
Maybe SoE will be less overcooked and a better album? I don't particularly like pop-rock, but Tedder is a very highly respected writer/producer for a reason. He is one of the best "new" (as in, came on the scene within the last 10 years) producers U2 could work with.
I'm reserving judgment at this point. Ultimately, it's going to come down to a couple things. 1) U2's own ability to write good songs (I'm inclined to believe they still have it) and 2) whether or not U2/their producer(s) overcook the album. It's less to do with the producer and more to do with the musicians themselves.
