Can I just add my own support for this - as has been stated elsewhere in 
this discussion, hard forks are difficult, and risky. The earlier we 
have a decision, and the earlier the change goes into the code, the 
easier that is.

Even if the decision was the actual block size change is fine to leave 
until 2020, I'd like to see the code committed ASAP so that every new 
install, and every upgrade from there on gets the new version.

My personal opinion only is that 7 transactions a second is insanely 
limited even if the main chain does nothing but act as a backbone 
between other chains and transaction networks. I don't think that's 
overly controversial. I think 2016 is too early for a 20mb block size, 
though. I'm inclined to suggest a schedule of expansion, say to 2mb in 
2016, 4mb in 2018, 8mb in 2020 and 20mb in 2022 where it stops. The 
intent would be to provide enough size pressure to motivate scaling 
work, while not limiting Bitcoin overly.

Further, I think this highlights that we need more work on fees. Right 
now fees and transactions included are fairly naive, but I'd like to see 
the absolute block size limit as a hard upper bound, with miners 
imposing soft limits based on a balance cost of storage, number of 
outputs vs inputs (and therefore impact on the UTXOs), and risk of 
orphan blocks to determine which transactions are actually worth 
including in each block. If anyone has numbers on block size vs orphan 
rate that would be really useful, BTW.
