They wont be back man, the window for Creed has closed. They were a band for 6 years then split for 6 years, then back for 3 years, now gone again for 5 years. It's hard to build a band up with momentum, touring and new songs especially these days. It would take real effort to get things to the point Creed could make a go again. I do not see any of the guys with the kind of time it needs to do that. I would hope they would not return just for a 1 off tour of old music either, that would be cold to do to fans who have held on for that new music since they were writing in 2010/2011. It seems as if the guys are at the point in life and careers that working with someone they dont want to work with, isn't a direction they want to take again. I appreciate that they did try again in 2009 to work with Stapp, it didn't work out. I will never forget when Creed came back in 2009, that was overwhelmingly awesome!
You make a lot of valid points but at the same time, it would be excellent to see Creed make a go of it with new music. I know it would take a lot to get the band to a place of success again, I'd like to think it could happen if the effort was put into it the proper way. It would take massive marketing, planning and touring for a long period of time for sure.
