For me it's bullshit when people say it's "too early to write new material." You write when you're inspired and feel in the right mood, there is no rule that the longer you wait the better the songs get. Back in the 60s/70s bands released two, or even three studio albums a year and those are among the most timeless albums of all time.
I find it a little sad that most acts see it as standard to wait three years between every release. I envy those of you who got to experience the times when your favorite bands basically threw material at the fans like once every six months.
