Well, although in some ways it pains me to say this, Kiss are currently a better live band than they have been since about 1978.
I've seen them many, many times (with various different line-ups) and their show at Download last year was the best I've ever seen them do in terms of the complete performance.
One word of warning - it does seem as though interest in these shows is way beyond anything I've known for Kiss in the UK since I've been into them (and that's a LONG time). This could end up being a very fast selling tour indeed.
Another thing, a strong rumour has emerged today suggesting it'll be a three band bill with Anvil and Steel Panther supporting!
