I'm in the exact same situation.
Aside from hoping it comes today.. my last glimmer of hope is that once the tracking number is updated, maybe the expected delivery will get changed to Saturday (there was one person here who also has "UPS Next Day Air" service, but with an expected Saturday delivery).
Yeah... i'm giving it one more hour (it's 7pm EST at the moment), until I mentally give up for today. Tomorrow would be nice too. And I'm sure if I don't get it tomorrow... Monday would look promising as well. hahahaha
