I've been waiting for this....   https://bitcointalk.org/index.php?topic=147933 ... and so it begins.

I'll make a prediction here-- the popularity of off-line transaction will mean that bitcoin fees never peak above 200 BTC/day averaged over a month.  In fact they may have already peaked-- more people use bitcoin now than ever before and yet the fee's have never passed 100BTC/day at seven day rolling average and seem to be declining when averaged over longer time spans.

Once electronic schemes like become popular for smaller amounts and large off-chain bank-like transfers for larger amounts there will be little reason for anyone to use on-chain for normal commercial transactions.
