I had a feeling they were going to make another black album. I knew Lars of Kirk would start whining about long songs, they are just too much brain power for them to play anymore. They want to make an album that makes lots of money, and easier to play.... just like with Mustaines abrupt songs on "13". They are slowing down, but they are not so old they can't play fast. The day they can't play fast anymore is the day they will retire because it's required for their music.
