Just change it to 26825 so miners don't mine for free for the next 5 days. It still gives everyone another day to prepare.
The hashrate is picking up. We need to make sure everyone gets a fair shot to upgrade before the hard fork.
If we changed now, we'd have to have everyone download another new wallet and pool operators would need to recompile again. Not ideal.
We're committed to 26850 at this point. We'll get there very soon!
