It's pretty clear that the lead developers want to raise the max block size.
Really? Why do you say that?
From what I've read it seems like a good idea because it will improve the network.
Really? Improve it how?
Anyways...... this requires a hard fork. Do you think the chances of this fork are 100% ?
No.
When do you think the fork will be?
If it happens, then my prediction is that it will be when there is less than a 75% chance of getting a 1kb or smaller transaction with inputs totaling more than 0.1 BTC included in the next block with a fee of 2%.*
