I would love a return to the guitar style of old, with the "riff-salad" principal of throwing loads of riffs into a single song, while still staying very coherent (TMI arguably has more riffs than The Gallery in that sense). Martin Brandström could ease a bit on the keyboards and let the electric and acoustic guitars do as much of the melody work as possible. It would be great for Mikael to use his clean voice again, and with what they learned from Projector, I'm sure they will meld into the songs even better. Also, this would finally have DT challenge themselves, which I don't feel has happened for a long time. Haven and DD were the product of a band that is very sure in themselves, and perfected what they do, so a risky, challenging take on songs is just what they need. Hours Passed in Exile is a perfect example of old-style DT riffing coupled with their modern approach, and it's a path I would like them to take for the next one.
