A BIP update should already have been rolled out. We can all see the effects already, with the usual 0.0001 BTC TX fee, we are starting to have to wait multiple blocks. Recently, I withdraw from a gambling site which forced me to use the 0.0001 TX fee, and it took me 6 hours to withdraw.
Good to see bitcoin changing, not just all proposed changes.
I tried withdrawing from a site that forced me to use the usual 0.0001 BTC TX fee, and getting a single confirmation took over an hour. My transaction was missed out of five blocks that were mostly crammed so full they were almost up to the 1MB limit. However, my transaction was also missed out of a few very small blocks that had plenty of room left to include it. The apparent spare capacity isn't always being used.
It was frustrating for me, but for noobs it could be a problem that puts them off Bitcoin. I understand that things are slowly changing, but a noob wouldn't.
