Random notes from Elon in a conference call today via reddit:

Really the 6th iteration of F9
Last major revision
Up to 300 more flights with block 5
2nd stage has block 5 engine but will operate like a block 4 for this flight
The interstage looks cool
Re-flying same block 5 core within 24 hours next year
Leg 2.0
No more aluminum grid fins
Elon confident that full reusability of the Second Stage is achievable.
Gaining data about 2nd stage entry now. They transmit to the Iridium constellation
Will add thermal protection system to 2nd stge
Fuel costs $300,000-400,000. Still hoping to get the marginal cost of a Falcon 9 launch down to $5-$6 million.
first stage 60 percent of cost, 2nd stage 20, fairing 10, everything else 10
Expecting no unnecessary action between flights. Fold up legs, attach 2nd stage and go.
First block 5 to 10 flights most likely next year. Big milestone Elon says.
Need to take this booster apart after this flight since it's the first Block 5
Human rated rockets must be overdesigned by 40% for crew safety
Boca Chica will be re-dedicated to BFR
30 to 50 Block 5 cores planned
SpaceX charging $50 million for flight proven flight, instead of $62 million for a new one.
NASA can be a pain in the ass sometimes
Load and Go issue has been overblown. CAN load fuel and then have astronauts board
Massive amount of research and testing in COPV 2.0. Most advanced pressure vessel ever developed by humanity.
