If you ask me they should release a greatest hits album, tour it, then call it a day. What I actually think will happen is:

Double disc Greatest Hits compilation next year. Basically Cross Road with a couple of changes so they can sell it again, and a new CD with "the best of" from These Days to The Circle including 2 new songs. Then a 2 year sellout worldwide "farewell" tour so they make sure it sells out while charging extortionate amounts for tickets. Have a break, do some solo albums, and then maybe reunite in 2015/2016 for either another album/tour.
