I've just read the newsletter, and I can't really understand the " Only YOU will discover the headline acts for MFAB2009 ahead of the normal information release in February/March" bit.
If you know the headline acts for next year, then the best way to encourage people to buy the EarlyBird tickets is to get that information into the public domain as soon as possible. I can understand waiting until the Rainbow Chasers gig to announce this as you'll have the EarliestBird ticket offer for concert goers, but to then hold onto the information until a general release in Feb/Mar is just daft.
If you know who is playing then you should really tell us as soon as you (contractually) can!!!
