Testnet is not going live tomorrow, Dawn 1.0 was completed like a week ago and that is what is being presented tomorrow., plus future plans i'm sure. Dawn 1.0 includes an early release of the Dev SDK for early Dev adopters to get started. Testnet should be live December. Why does everyone think the testnet is going live tomorrow when they updated this release schedule months ago. so many places to get correct information. here is one link that shows the progress of the testnet ("Dawn 2.0") https://github.com/EOSIO/eos/milestones
