I'm also waiting on a payout. My confirmed is above my threshold and has been for awhile now. Maybe the payment script has not run yet.
Yeah, at this point anyone who leaves is going to miss out on coins when it finally hits, and anyone who sticks around is going to get more than their average. Right now I'm sitting around 0.045 for this block, usually I average around 0.015. This is with 27mhash/s on a HD 4670.
