No, they just didn't make WIITB part 2 so people stopped listening. Which sucks as SHTS is amazing and the EP followed that direction. Saw them at Soundwave after they reunited and dropped the EP and they sounded awesome. So sad they are no more... again..
Say hello to sunshine is my favorite album of theirs, so it had nothing to do with me wanting WIITB part 2.. everything post say hello to sunshine sucked in my opinion.
