Hate to break it to you guys, but I think there wont be a fake karakura standoff/ichigo vs ulquiorra for at least a few episodes:
 Betrayal! Aizen`s Secret Maneuvers 17.03.2009
 Rescue Hirako! Aizen vs. Urahara 24.03.2009
 The Karakurizer is Born 31.03.2009 WTF?!?!?!?!?!?!
I pray to the king of SS this arc wont be as long as the suck-ass bakuto-arc...
