That's too broad of a statement to bet against.
They might deliver "something" after a long wait and much rage, but it will be nowhere near the specs listed on the sales page. (which in itself will cause a shitstorm like no other on these forums)
Alright then, what terms would you like to add to the bet?
Something like:
BFL will deliver an SC Single capable of producing at least 20GH/s, a Jalepeno capable of producing at least 1.75GH/s, and a mini-rig capable of producing at least 500GH/s.
