Will there be a Glee live 2012 tour?

I went to the Glee tour at the O2 yesterday and I had an amazing time!
The only downside is I didn't have great seats as I was sat in the top
balconies, and I couldn't see the cast :(

Do you think there'll be another tour in 2012? Do you think they'll
come to London  is there any speculation that there will be another?

Thank you!
