ABC headlining 2009?

I am a little amazed that ABC are not only returning,but headlining this year. They were very good last year,but, I would like to see Berlin do all the dates as the headliners this time around. ABC put on a great show, but it seems to me that Berlin,who have more hits, and draw a bigger crowd,would be the best choice for headliner. I look forward to seeing both bands this time out.
