Some Rammstein Questions?

I have been listening to Rammstein (the band) for two years now and I am now 14. I recently figured out that one of my friends at school listens to them as well. I wanted to know if they are going to tour in 2014 and if they might come to America (probability) and If they might come I knew that if I went and they played the song p**** my parents would not really approve. However my parents don't about the song. My friend and I have been thinking also what is the experience like? How much the tickets are going to cost? And Should I still go even though there will be a chance they might play the song and pull out the -certain- cannon? Thanks to all who answered.
