I think we're jumping the gun here a bit on how they are going to meld the new and old. Obviously we have no idea what that exactly means but take for example what their new sound and internal dialog/personalized lyrics may mean. I HIGHLY doubt we're ever going to get another "one step closer to the edge" brand of lyrics again as a whole album. Personal lyrics don't always have to be angst-ridden to be powerful. Trials through drugs, marriage and children etc. have no doubt had an effect on all of them during the 13 years since HT. If there's one thing I've seen (and most of us have) is that these guys are introspective to what they are trying to do, musically and otherwise, even if it's vague before the album drops. There are very few 'artists' out there that I'll buy into over and over again, the Chris Nolans, Stephen Kings and among them I place LP personally. They've earned the benefit of the doubt.
