Just came across this video which helped me alot understanding the blocksize limit issue:
http://keepbitcoinfree.org/I found it quite amazing that Peter Tood came with it even before Gavin ran his tests about it and on his own..
From what i've seen on the bitcoin-dev logs, it seems gmaxwell just dont see the need for increasing the blocksize now, for there is still quite some place left. You dont fork the perfectly working bitcoin network in anticipation like that.
+ there is this argument that once the fork of 20MB is made, why not just consider infinite limit.
IMHO Gavin has been pressurized by (private) business' interests such as Bitpay, Coinbase et al to push this (NYSE, CIA, and USgov too?!), but i am glad there is still some space to argue and not despotically rush into it.
Consensus. Love that word.

ps: just trying to get it as i only aspire for bitcoin to succeed and grasp what this is all about since im invested in, so feel free to correct me if wrong.
